Q. With reference to the triangle, is not the Âtmâ-Buddhi-Manas different for each entity, according to the plane on which he is?
A. Each Principle is on a different plane. The Chelâ must rise to one after the other, assimilating each, until the three are one. This is the real root of the Trinity.
Q. In The Secret Doctrine we are told that Âkâsha is the same as Pradhâna. Âkâsha is the Auric Egg of the earth, and yet Âkâsha is Mahat. What that is the relation of Manas to the Auric Egg?
A. Mûlaprakriti is the same as Âkâsha (seven degrees). Mahat is the positive aspect of Âkâsha, and is the Manas of the Kosmic Body. Mahat is to Âkâsha as Manas is to Buddhi, and Pradhâna is but another name for Mûlaprakriti.
The Auric Egg is Âkâsha and has seven degrees. Being pure abstract substance, it reflects abstract ideas, but also reflects lower concrete things.
The Third Logos and Mahat are one, and are the same as the Universal Mind, Alaya.
The Tetraktys is the Chatur Vidyâ, or the fourfold knowledge in one, the four-faced Brahmâ.

Q. Have the Nâdîs any fixed relationship to the vertebræ; can they be located opposite to or between any vertebræ? can they be regarded as occupying each a given and fixed extent in the cord? Do they correspond to the divisions of the cord known to Anatomists?
A. H. P. B. believed that the Nâdîs corresponded to regions of the spinal cord known to Anatomists. There are thus six or seven Nâdîs or plexuses along the spinal cord. The term, however, is not technical but general, and applies to any knot, centre, ganglion, etc. The sacred Nâdîs are those which run along or above Sushumnâ. Six are known to Science, and one (near the atlas) unknown. Even the Târaka Râja Yogîs speak only of six, and will not mention the sacred seventh.
