The yogic practices of the ‘Kalacakratantra’ are a form of inner
sacrifice, in which regenerative fluids, sometimes called ‘soma’, are
the inner offering to the deities dwelling within one’s own body. Likewise,
in this rite of inner sacrifice, ‘candali’, or the fire of gnosis, is
a purifying fire to which all of one’s imperfections are offered. Being the
inner sacrifice, it is the most powerful and expedient means to spiritual realisation. –sauce
