“25. HOW DID THE MANASA, THE SONS OF WISDOM ACT? THEY REJECTED THE SELF-BORN (THE BONELESS). THEY ARE NOT READY. THEY SPURNED THE (FIRST) SWEAT-BORN. THEY ARE NOT QUITE READY. THEY WOULD NOT ENTER THE (FIRST) EGG-BORN.
To a Theist or a Christian this verse would suggest a rather theological idea: that of the Fall of the Angels through Pride. In the Secret Doctrine, however, the reasons for the refusal to incarnate in half-ready physical bodies seemed to be more connected with physiological than metaphysical reasons.
Not all the organisms were sufficiently ready. The incarnating powers chose the ripest fruits and spurned the rest.
26. WHEN THE SWEAT-BORN PRODUCED THE EGG-BORN, THE TWO-FOLD (ANDROGYNE THIRD RACE), THE MIGHTY, THE POWERFUL WITH BONES, THE LORDS OF WISDOM SAID: “NOW SHALL WE CREATE.”
27. (THEN) THE THIRD (RACE) BECAME THE VAHAN (VEHICLE) OF THE LORDS OF WISDOM. IT CREATED SONS OF “WILL AND YOGA”, BY KRIYASAKTI IT CREATED THEM, THE HOLY FATHERS, ANCESTORS OF THE ARHATS…
How did they create, since the “Lords of Wisdom” are identical with the Hindu Devas, who refuse “to create”?
It was by Kriyasakti, that mysterious and divine power latent in the will of every man, and which, if not called to life, quickened and developed by yogi-training, remains dormant in 999,999 men out of a million, and gets atrophied.
This power is explained in “The Twelve Signs of the Zodiac” as follows: “Kriyasakti” – the mysterious power of thought which enables it to produce external, perceptible, phenomenal results by its own inherent energy.
The ancients held that any idea will manifest itself externally, if one’s attention (and Will) is deeply concentrated upon it; similarly, an intense volition will be followed by the desired result.”
