Goddess Maa Kali: “Another manifestation of goddess Maa Durga. She killed the demon named Raktabij which represents human desires. These desires detract man from following the spiritual path. Yogically She is the primordial Female Energy. She is the kinetic state of Prana from whom creation emanates. Common man considers worldly knowledge to be actual knowledge, for this reason Kali has been depicted as black because in her state of first manifestation, worldly knowledge did not evolve amidst creation.
Her lolling tongue is symbol of Khecari mudra of a yogi. The falchion in her left hand symbolizes the annihilation of ignorance of a yogi and entry into the realm of knowledge. Practicing ardent Kriya a yogi attains soul-realization, then he achieves omniscience. The 108 garland of demon heads indicate the 108 bestial proclivities in man. These devilish propensities have evolved from the kinetic state of Prana within man and deter him from remaining materially detached. But when Prana is still, the activities of these devilish propensities cease, this cessation of activity is symptomatic of destruction. Therefor Kali has been depicted with the falchion severing the 108 demons. This severance of ignorance is necessary, for a yogi is purified and attains soul-knowledge.
