speak more correctly, the power or force above described, the
impressions of the mental states therein, and the notion of
self-identity or Ahankaram generated by their collective operation.
This principle is called merely physical intelligence in the
"Fragments." I do not know what is really meant by this expression. It
may be taken to mean that intelligence which exists in a very low state
of development in the lower animals. Mind may exist in different stages
of development, from the very lowest forms of organic life, where the
signs of its existence or operation can hardly be distinctly realized,
up to man, in whom it reaches its highest state of development.

In fact, from the first appearance of life* up to Tureeya Avastha, or
the state of Nirvana, the progress is, as it were, continuous.

* In the Aryan doctrine, which blends Brahmam, Sakti, and Prakriti in
one, it is the fourth principle then, in the Buddhist esotericisms the
second in combination with the first.

We ascend from that principle up to the seventh by almost imperceptible
gradations. But four stages are recognized in the progress where the
change is of a peculiar kind, and is such as to arrest an observer's
attention. These four stages are as follows:--

(1) Where life (fourth principle) makes its appearance.

(2) Where the existence of mind becomes perceptible in conjunction with
life.

(3) Where the highest state of mental abstraction ends, and spiritual
consciousness commences.

(4) Where spiritual consciousness disappears, leaving the seventh
principle in a complete state of Nirvana, or nakedness.

According to our philosophers, the fifth principle under consideration
is intended to represent the mind in every possible state of
development, from the second stage up to the third stage.

IV. Brahmam and Sakti. This principle corresponds to your "spiritual
intelligence." It is, in fact, Buddhi (I use the word Buddhi not in the
ordinary sense, but in the sense in which it is used by our ancient
philosophers); in other words, it is the seat of Bodha or Atmabodha.
One who has Atmabodha in its completeness is a Buddha. Buddhists know
very well what this term signifies. This principle is described in the
"Fragments" as an entity coming into existence by the combination of
Brahmam and Prakriti. I do not again know in what particular sense the
word Prakriti is used in this connection. According to our philosophers
