We have considered the manifested Logos in the Universe. We shall now
consider His manifestation in Man, the microcosm. The teachings are all
collected from the Upanishads.
(i.) -- _The manifestation in the heart._ -- A detailed knowledge of
this manifestation is called Dahara Vidya in Chandogya. The Upanishads
speaks of Atma in the cavity of the heart.
"Guhahitam Gahvarestham Puranam" is a well-known passage from the
Upanishads. The Purusha in the heart is also called Pradesa or the
span-sized Purusha and is the favourite object of meditation in
Pauranika Upasana. The Upanishads call Him thumb-sized and there is an
interesting discussion as to the size in Sariraka Sutras I-3-24 to 26
and the Bhashya thereupon.
(ii.) -- _The Manifestation in the Pranas._ -- The Upanishads say: --
"It is this Prana that is consciousness itself, Bliss, without
infirmities and death."
"They are these five Brahma Purushas."
