Whilst Brahma formerly, in the beginning of the Kalpas, was meditating on creation, there appeared a creation beginning with ignorance and consisting of darkness.... Brahma, beholding that it was defective, designed another; and whilst he thus meditated, the animal creation was manifested.... Beholding this creation also imperfect, Brahma again meditated, and a third creation appeared, abounding with the quality of goodness.
The objective manifestation follows the mental meditation; first idea, then form. Hence it will be seen that the notion current among many Theosophists that Devachan is waste time, is but one of the illusions due to the gross matter that blinds them, and that their impatience of the idea of Devachan arises from the delusion that fussing about in gross matter is the only real activity. Whereas, in truth, all effective action has its source in deep meditation, and out of the Silence comes ever the creative Word. Action on this plane would be less feeble and inefficient if it were the mere blossom of the profound root of meditation, and if the Soul embodied passed oftener out of the body into Devachan during earth-life, there would be less foolish action and consequent waste of time. For Devachan is a state of consciousness, the consciousness of the Soul escaped for awhile from the net of gross matter, and may be entered at any time by one who has learned to withdraw his Soul from the senses as the tortoise withdraws itself within its shell. And then, coming forth once more, action is prompt, direct, purposeful, and the time “wasted” in meditation is more than saved by the directness and strength of the mind-engendered act.
Devachan is the sphere of the mind, as said, it is the land of the Gods, or the Souls. In the before quoted “Notes on Devachan” we read:
There are two fields of causal manifestations: the objective and the subjective. The grosser energies find their outcome in the new personality of each birth in the cycle of evoluting individuality. The moral and spiritual activities find their sphere of effects in Devachan.
As the moral and spiritual activities are the most important, and as on the development of these depends the growth of the true Man, and therefore the accomplishing of “the object of creation, the liberation of Soul”, we may begin to understand something of the vast importance of the devachanic state.
When the Triad has shaken off its last garment, it crosses the threshold of Devachan, and becomes “a Devachani”. We have seen that it is in a peaceful dreamy state before this passage out of the earth sphere, the “second death”, or “pre-devachanic unconsciousness”. This condition is otherwise spoken of as the “gestation” period, because it precedes the birth of the Ego into the devachanic life. Regarded from the earth-sphere the passage is death, while regarded from that of Devachan it is birth. Thus we find in “Notes on Devachan”:
