T. Subba Row on spiritual development:
“Good works on the physical plane helps with our spiritual development. First, by its influence on the formation of habits (…) Secondly, by its effects on both the astral and the physical plane, a good action has the effect of concentrating good effects on the doer. When a man makes bad Karma, by the very ideation he attracts to himself forces, which will lead from bad to worse. A man, who has good ideas, attracts influences of quite a different kind and these will help him on the way. On the other hand, actions must not be judged of by their effects alone, because then one element is wanting; the inward impulse prompting the act, must be also taken into consideration.” (T. Subba Row, Esoteric Writings of T. Subba Row. Second Edition, pp. 125-126)
William Q. Judge states, that universal brotherhood is “the effort to convert our lower nature into higher nature, and thus to aid in the great process of evolution going on throughout the macrocosm.” (William Quan Judge, Echoes of the Orient, Vol. 3, pg. 128. 1975-87.)
A LETTER VERBATIM FROM THE SECRET DOCTRINE
“It becomes patent why we could not perceive, even with the help of the best earthly telescopes, that which is outside our world of matter. Those alone, whom we call adepts, who know how to direct their mental vision and to transfer their consciousness — physical and psychic both — to other planes of being, are able to speak with authority on such subjects. And they tell us plainly: —
“Lead the life necessary for the acquisition of such knowledge and powers, and Wisdom will come to you naturally. Whenever your are able to attune your consciousness to any of the seven chords of‘Universal Consciousness,’ those chords that run along the sounding-board of Kosmos, vibrating from one Eternity to another; when you have studied thoroughly ‘the music of the Spheres,’ then only will you become quite free to share your knowledge with those with whom it is safe to do so. Meanwhile, be prudent. Do not give out the great Truths that are the inheritance of the future Races, to our present generation. Do not attempt to unveil the secret of being and non-being to those unable to see the hidden meaning of Apollo‘s HEPTACHORD — the lyre of the radiant god, in each of the seven strings of which dwelleth the Spirit, Soul and Astral body of the Kosmos, whose shell only has now fallen into the hands of Modern Science. . . . . . Be prudent, we say, prudent and wise, and above all take care what those who learn from you believe in; lest by deceiving themselves they deceive others . . . . . for such is the fate of every truth with which men are, as yet, unfamiliar. . . . Let rather the planetary chains and other super-and sub-cosmic mysteries remain a dreamland for those who can neither see, nor yet believe that others can. . . .”
