Outer offerings of animals stand for the mechanical religion that spends itself on ceremony while the inner life is left untouched, and this the higher awareness does not want. The ram, the bullock, the lamb, the goat are the animal energies of a person, brought and slaughtered as ritual instead of being transformed within. Piling up such acts changes nothing when the consciousness behind them stays unaltered. What is asked is not more offering but a change of the one who offers.
The divine within takes no pleasure in blood shed on an altar of habit. The work that matters is the inward one, where the animal in a person is not merely killed by rule but raised into something higher.
Rams: the driving animal force in a person, offered by ritual instead of transformed
Bullocks: the heavy laboring strength of the lower nature, spent on ceremony
Lambs: the mild instinctive life brought to the altar of habit
He goats: the rank untamed appetite, slaughtered by rule while the self stays unchanged
