The ancient Greek philosopher, Democritus, propounded an hypothesis of the constitution of matter, and gave the name of atoms to the ultimate unalterable parts of which he imagined all bodies to be constructed. In the 17th century, Gassendi revived this hypothesis, and attempted to develope it, while Newton used it with marked success in his reasonings on physical phenomena; but the first who formed a body of doctrine which would embrace all known facts in the constitution of matter, was Roger Joseph Boscovich, of Italy, who published at Vienna, in 1759, a most important and ingenious work, styled Theoria Philosophiæ Naturalis ad unicam legem virium, in Natura existentium redacta. This is one of the most profound contributions ever made to science; filled with curious and important information, and is well worthy of the attentive perusal of the modern student. In more recent days, the theory of Boscovich has received further confirmation and extension in the researches of Dalton, Joule, Thomson, Faraday, Tyndall, and others.

The views expressed in this Grammar on the fundamental concepts of science, especially on those of force and matter, have formed part of the author's teaching since he was first called upon (1882) to think how the elements of dynamical science could be presented free from metaphysics to young students. But the endeavour to put them into popular language only dates from... 1891...

My conviction is the result of my study, over many years, of the Ageless Wisdom Teachings. This body of teachings was given to the world by the Masters of Wisdom, in particular, that phase of them which was released to the world by the Tibetan Master, Djwhal Khul, through an English disciple, Alice A. Bailey, between 1919 and 1949... a body of teachings which follows sequentially on those given through Madame Helena Petrovna Blavatsky, founder of the Theosophical Society, between 1875 and 1889. The Theosophical teachings were the preparatory phase of the Ageless Wisdom Teachings... The Tibetan Master... predicted a further, revelatory, phase which He said would emerge worldwide... some time after 1975... revelations coming from the Masters, and above all from the Master of all the Masters, the Lord Maitreya, Who embodies the Christ Principle and is, therefore, the Christ on our planet. p. 2

In the sixth century B.C., Gautama, an Aryan princeling on the northern frontier of India, formulated a bleakly pessimistic philosophy that markedly resembles Schopenhauer's. This high doctrine of negation, for reasons that would require an extensive historical explanation, became extremely popular, but was variously interpreted by at least eighteen rival schools, each of which claimed alone to preserve the true teaching of Gautama the Buddha, and Gautama's austere atheism was gradually contaminated and obscured by the usual theological techniques, so that a philosophy that was intended to supplant religion was converted into just another elaborate and learned superstition.

Zoroaster taught it to his followers in Persia twenty-five hundred years ago. Confucius preached it in China twenty-four centuries ago. Lao-tse, the founder of Taoism, taught it to his disciples in the Valley of the Han. Buddha preached it on the bank of the Holy Ganges five hundred years before Christ. The sacred books of Hinduism taught it a thousand years before that. Jesus taught it among the stony hills of Judea nineteen centuries ago. Jesus summed it up in one thought — probably the most important rule in the world: “Do unto others as you would have others do unto you.

Undoubtedly the sacrifice of Christ and his acceptance of crucifixion for the sake of bringing the Teaching of Light had tremendous significance for all humanity on all planes of existence. Sacrifices and great achievements were also performed by other Great Teachers for humanity's sake. And it is difficult to say whose sacrifice was greater—the sacrifice of Sri Krishna, the Spiritual Teacher and kingly builder of life, or the sacrifice of Guatama Buddha, who, during more than sixty years, bore the heavy burden of teaching for the affirmation of the great Law...

What he taught may be summed up in a few words, as the perfume of many roses may be distilled into a few drops of attar: Everything in the world of Matter is unreal; the only reality is in the world of Spirit.

We do not have even fragments of the teachings of former World Teachers given prior to certain knowledge of Their existence. We do not have the teachings of a Christ, or a Buddha, or a Krishna, except seen through the eyes of later followers. For the first time we are given the flavor of the thoughts and insights of a Being of immeasurable stature to enable us to understand the path of evolution stretching ahead of us which He has come to outline for us. The impression left in the mind by the Teacher is that the breadth and depth of His knowledge and awareness have no limits; that He is tolerant and wise beyond conception, and of amazing humility.

The first thinker to introduce the purely monistic conception of substance into science and appreciate its profound importance was the great philosopher Baruch Spinoza; his chief work appeared shortly before his death in 1677, just one hundred years before Lavoisier gave empirical proof of the constancy of matter by means of the chemist's principle instrument, the balance. In his stately pantheistic system the notion of the world (the universe, or the cosmos) is identical with the all-pervading notion of God; it is at one and the same time the purest and most rational monism and the clearest and most abstract monotheism. This universal substance, this “divine nature of the world,” shows us two different aspects of its being, or two fundamental attributes — matter (indefinitely extended substance) and spirit (the all-embracing energy of thought). All the changes which have since come over the idea of substance are reduced, on a logical analysis, to this supreme thought of Spinoza's; with Goethe I take it to be the loftiest, profoundest, and truest thought of all ages. [Original in German: Der erste Denker, der den reinen monistischen »Substanzbegriff« in die Wissenschaft einführte und seine fundamentale Bedeutung erkannte, war der große Philosoph Baruch Spinoza; sein Hauptwerk erschien kurz nach seinem frühzeitigen Tode, 1677,...]

At the beginning or end of each age, the Hierarchy of Masters send one of Their Great Ones into the world to act as a teacher for the coming time. We know some of these great teachers historically as Hercules, Hermes, Rama, Mithra, Confucius, Zoroaster, Vyasa, Krishna, Buddha, the Christ, and Mohammed.

To my mind, the Agni Yoga teachings constitute one of the major attempts of Hierarchy to prepare humanity for the new age. They are entirely relevant to the present----and future time. The first book of the series, The Call, was given by Maitreya Himself, and was intended to alert disciples to the fact of His imminent return. The Master Morya, as I have said elsewhere, is one of the first group of Masters to be seen by humanity, and is the stimulus behind the occult groups of all kinds. His immediate task is to regenerate and purify the teaching of these groups... [The Agni Yoga Teachings were given] by mental telepathy through Helena Roerich (a disciple of the Master Morya) in Russian... My information is that The Call is His [Maitreya's] sole personal contribution to the Agni Yoga series.. The Call is also titled: Leaves of Morya’s Garden, I. (p. 300/1)

The Rigveda stated that the earth was a ...globe suspended freely in space. The Vedic texts disclosed that the Sun held the earth and heavenly bodies in its orbit. The Shatapatha Brahmana, a treatise of untold antiquity, recognized and explained the fact that the earth was spherical.. Aryabhata explained the daily rising and setting of planets and stars in terms of the earth’s constant revolutionary motion. The Surya Siddhantha said that the earth, owing to its gravitational force draw all things to itself. In physics, the thinker Kanada, explained light and heat as different aspects of the same element, thus anticipating Clarke Maxwell's Electro-magnetic Theory, which unified different forms of radiant energy. Sankaracharya, in his Advaita thought expanded the concept of unity of matter and energy. Vacaspati recognized light as composed of minute particles emitted by substances, anticipating Newton’s Corpuscular Theory of Light and the later discovery of the Photon. In Botany, Sankara Mishra and Kanada have discussed the circulation of sap in the Plant and the Santiparva of Mahabharata has clearly stated that the plants develop on the strength of nutrients made through interaction of sunlight and materials obtained from the air and ground. Bhaskarcharya's concept of Differential Calculus preceded Newton by many centuries. His study of time identified Truti: The 3400th part of a second as the unit of time.

There has probably never been a period in the history of thought entirely resembling the present. Thinkers everywhere are conscious of two things, first, that the region of mystery has never before been so clearly defined, and secondly, that that region can be entered more easily than has hitherto been the case; it may, therefore, perhaps be induced to render up some of its secrets if investigators of all schools pursue their search with determination. The problems with which we are faced, as we study the known facts of life and existence, are susceptible of clearer definition than heretofore, and though we do not know the answers to our questions, though we have not as yet discovered the solutions to our problems, though no panacea lies ready to our hand whereby we can remedy the world's ills, yet the very fact that we can define them, that we can point in the direction in which mystery lies, and that the light of science, of religions, and of philosophy, has been shed upon vast tracts which were earlier considered lands of darkness, is a guarantee of success in the future. We know so much more than was the case five hundred years ago, save in a few circles of wise men and mystics; we have discovered so many laws of nature, even though as yet we cannot apply them; and the knowledge of "things as they are" (and I choose these words very deliberately) has made immense strides. Lecture II, The Evolution of Substance

The Theosophical conception, as widely put forward among thoughtful people, asks them to consider the coming of World Teachers as normal, not as abnormal; as under a certain definite law, and not as a breach of continuity; as part of the Divine plan working out in human evolution, by which these Teachers form a long succession, appearing at quite definite intervals, and accompanied by certain definite signs or conditions in the civilization of the world to which they come. Theosophists, looking back over the world's religions, pointed out that each religion had such a great Teacher as its Founder; that no matter where you searched in the past, you found some magnificent figure at the commencement of a new era alike of religion and civilization; that you could trace a definite order; that you could recognize a quite intelligible sequence of world religions, rising one after another and appearing in the world when the previous civilization and religion was beginning to show signs of failing in its power, and of no longer being able thoroughly to cope with the conditions surrounding it. p. 126
