In all that concerns chastity and marriage their principles are of the utmost purity. Everywhere the great teacher recommends chastity and temperance… - Annie Besant

Moreover these same disciples and their earliest colleagues wrote down from memory all the public sayings and parables of the Master that they had heard, and collected with great eagerness any reports they could find, writing down these also, and circulating them all among those who gradually attached themselves to their small community. Various collections were made, any member writing down what he himself remembered, and adding selections from the accounts of others. The inner teachings, given by the Christ to His chosen ones, were not written down, but were taught orally to those deemed worthy to receive them, to students who formed small communities for leading a retired life, and remained in touch with the central body. p. 140

Quickly or slowly, according as that probation is lived nobly or poorly, another summons comes to him, when the Master sees that he has gained to a considerable extent the Qualifications which are necessary, and needs a further fuller teaching in order that he may apply his knowledge more efficiently to life. Again he is called; again he sees his Master. And then the Master accepts him as disciple, no longer on probation, but accepted and approved; now his consciousness is to begin to blend with the consciousness of his Master, and he is to feel His presence more clearly. p.63

S. Clement of Alexandria says quite bluntly, after alluding to the Mysteries: "Even now I fear, as it is said, 'to cast the pearls before swine, lest they tread them underfoot, and turn and rend us.' For it is difficult to exhibit the really pure and transparent words respecting the true Light to swinish and untrained hearers." (Clarke's Ante-Nicene Christian Library, Vol. IV. Clement of Alexandria. Stromata, bk. I., ch. xii.)
