What the Master did say on this is as follows: “The ‘dream of _devachan_’ lasts until karma is satisfied in that direction. In _devachan_ there is a gradual exhaustion of force. The stay in _devachan_ is proportionate to the unexhausted psychic impulses originated in earth life. Those whose actions were preponderatingly material will be sooner brought back into rebirth by the force of _Tanha_.” _Tanha_ is the thirst for life. He therefore who has not in life originated many psychic impulses will have but little basis or force in his essential nature to keep his higher principles in _devachan_. About all he will have are those originated in childhood before he began to fix his thoughts on materialistic thinking. The thirst for life expressed by the word _Tanha_ is the pulling or magnetic force lodged in the _skandhas_ inherent in all beings. In such a case as this the average rule does not apply, since the whole effect either way is due to a balancing of forces and is the outcome of action and reaction. And this sort of materialistic thinker may emerge out of _devachan_ into another body here in a month, allowing for the unexpended psychic forces originated in early life. But as every one of such persons varies as to class, intensity and quantity of thought and psychic impulse, each may vary in respect to the time of stay in _devachan_. Desperately materialistic thinkers will remain in the devachanic condition stupefied or asleep, as it were, as they have no forces in them appropriate to that state save in a very vague fashion, and for them it can be very truly said that there is no state after death so far as mind is concerned; they are torpid for a while, and then they live again on earth. This general average of the stay in _devachan_ gives us the length of a very important human cycle, the Cycle of Reïncarnation. For under that law national development will be found to repeat itself, and the times that are past will be found to come again.
