[Bhur is the main system of Triloki. The Varaha Avatara restored the
system after the Kalpa Pralaya. Bhur being the lowest of the Seven Lokas
corresponds to Prithvi Tatva and hence to the sense of smell. The boar
is pre-eminently the animal of smell. The materialisation of the Prithvi
principle for the purpose of globe formation was an effort of the energy
of the Logos and the _smelling_ out of Bhur by the Varaha is suggestive.
The Globe evolution is preparatory to Monadic evolution. The pent up
Karma of the previous Kalpa develops itself on the Globes. All beings
are mutually interdependent for their evolution. They help one another
in the work of evolution, and one makes sacrifices that the others may
grow. Some have to wait, till others come forward. Then they become
united in the further race for progress. This great cosmic process, this
mutual sacrifice is Yajna itself, which is typified in the Boar
Incarnation. The Vedic Yajna gives prominence to the Communion of men
with Devas, as at the early stages this is an all important fact of
evolution. The Varaha is called the first Yajna Avatara and all the
parts of His body are named with reference to Vedic Yajna, as He by
raising Bhur prepared the field for Karma.]
