Parashat Tzav - The Secret of the Perpetual Fire and True Enthusiasm

"A perpetual fire shall be kept burning on the altar, it shall not be extinguished" (Leviticus 6:6)

The soul comes from the upper realms, the soul descended to the world in order to withstand tests, "The soul that You have given within me is pure...". The soul is higher than the angels, it was created before the angels. In the future to come, everyone will have dominion over the angels. Angels cannot ascend from level to level; rather, just as Hashem created them at the beginning of creation, so they remain for all eternity.

And a person, in order to ascend from level to level, must take all the lusts that burn within him and turn them into flames of fire, "A perpetual fire shall be kept burning on the altar, it shall not be extinguished"
