A true spiritual man is one who lives for Infinity, and whose presence creates peace. If your presence doesn't work, nothing works.

The truly spiritual man is indeed something of an oddity. He lives not for himself but to promote the interests of Another. He seeks to persuade people to give all to his Lord and asks no portion or share for himself. He delights not to be honored but to see his Saviour glorified in the eyes of men. His joy is to see his Lord promoted and himself neglected. He finds few who care to talk about that which is the supreme object of his interest, so he is often silent and preoccupied in the midst of noisy religious shoptalk. For this he earns the reputation of being dull and overserious, so he is avoided and the gulf between him and society widens. He searches for friends upon whose garments he can detect the smell of myrrh and aloes and cassia out of the ivory palaces, and finding few or none he, like Mary of old, keeps these things in his heart.

While you are a man, live the life of a man, and when you become a spirit, live the life of a spirit. But do not seek to mix the two together like oil and wine, and thus spoil both.

None believeth in the soul of man, but only in some man or person old and departed. Ah me! no man goeth alone. All men go in flocks to this saint or that poet, avoiding the God who seeth in secret. They cannot see in secret; they love to be blind in public. They think society is wiser than their soul, and know not that one soul, and their soul, is wiser than the whole world.

The sense that a man is serving a Higher than himself, with a service which will become ever more and more perfect freedom, evokes more profound, more humbling, more exalted emotions than any thing else in the world can do. The spirit of man is an instrument which cannot give out its deepest, finest tones, except under the immediate hand of the Divine Harmonist.

Feeling the unity of himself and the universe, the man who lives in spirit is no more a separate and self-centered individual but a vehicle of the universal spirit. [Like the artist, the moral hero does not turn his back on the world. Instead], He throws himself on the world and lives for its redemption, possessed as he is with an unshakable sense of optimism and an unlimited faith in the powers of the soul.

Spirit in its human manifestation is man’s response to his You. Man speaks in many tongues - tongues of language, of art, of action - but the spirit is one; it is response to the You that appears from the mystery and addresses us from the mystery. Spirit is word. And even as verbal speech may first become word in the brain of man and then become sound in his throat, although both are merely refractions of the true event because in truth language does not reside in man but man stands in language and speaks out of it - so it is with all words, all spirit. Spirit is not in the I but between I and You. It is not like the blood that circulates in you but like the air in which you breathe. Man lives in the spirit when he is able to respond to his You. He is able to do that when he enters into this relation with his whole being. It is solely by virtue of his power to relate that man is able to live in the spirit.

Later, when the [human] race sees its problem with clarity, it will act with wisdom, and train with care its Observers and Communicators. These will be men and women in whom the intuition has awakened at the behest of an urgent intellect; they will be people whose minds are so subordinated to the group good, and so free from all sense of separativeness, that their minds present no impediment to the contact with the world of reality and of inner truth. They will not necessarily be people who could be termed "religious" in the ordinary sense of that word, but they will be men of goodwill, of high mental calibre, with minds well stocked and equipped; they will be free from personal ambition and selfishness, animated by love of humanity, and by a desire to help the race. Such a man is a spiritual man. p. 181

A physical man does not receive the things of the spirit of God, for they are foolishness to him; and he cannot get to know [them], because they are examined spiritually. However, the spiritual man examines indeed all things, but he himself is not examined by any man.

The Great Man... is colder, harder, less hesitating, and without fear of 'opinion'; he lacks the virtues that accompany respect and 'respectability,' and altogether everything that is the 'virtue of the herd.' If he cannot lead, he goes alone... He knows he is incommunicable: he finds it tasteless to be familiar... When not speaking to himself, he wears a mask. There is a solitude within him that is inaccessible to praise or blame.

How amazing is the spirit of man!...it is impossible to lose hope for him. In the midst of disaster he has not lost his dignity or his faith in the values he cherished. Plaything of nature's mighty forces, less than a speck of dust in this vast universe, he has hurled defiance at the elemental powers, and with his mind, cradle of revolution, sought to master them. Whatever gods there may be, there is something godlike in man, as there is something of the devil in him.
The future is dark, uncertain. But we can see part of the way leading to it and can tread it with firm steps, remembering that nothing that can happen is likely to overcome the spirit of man which has survived many perils. Remembering also that life, for all its ills, has joy and beauty, and we can always wander,if we know how to, in the enchanted woods of nature.

The most spiritual men, as the strongest, find their happiness where others would find their destruction: in the labyrinth, in hardness against themselves and others, in experiments. Their joy is self-conquest: asceticism becomes in them nature, need, and instinct. Difficult tasks are a privilege to them; to play with burdens that crush others, a recreation. Knowledge–a form of asceticism. They are the most venerable kind of man: that does not preclude their being the most cheerful and the kindliest.

There are two men in each one of us: the scientist, he who starts with a clear field and desires to rise to the knowledge of Nature through observations, experimentation and reasoning, and the man of sentiment, the man of belief, the man who mourns his dead children, and who cannot, alas, prove that he will see them again, but who believes that he will, and lives in the hope – the man who will not die like a vibrio, but who feels that the force that is within him cannot die.

Of course man is useful to man, because his body is a marvellous machine and his mind an organ of wonderful efficiency. But he is a spirit as well, and this spirit is truly known only by love. When we define a man by the market value of the service we can expect of him, we know him imperfectly. With this limited knowledge of him it becomes easy for us to be unjust to him and to entertain feelings of triumphant self-congratulation when, on account of some cruel advantage on our side, we can get out of him much more than we have paid for. But when we know him as a spirit we know him as our own. We at once feel that cruelty to him is cruelty to ourselves, to make him small is stealing from our own humanity...
