101, 102. Maṇipūrāntaruditā & Viṣṇugranthivibhedinī
Devi resides in the Maṇipūra cakra and there She cuts as under the knot of Viṣṇu.
The knot of Viṣṇu is a sense of identification of one's emotions, feelings and thoughts with oneself. Maṇipūra is the seat of fire. Devi manifests Herself as Durgā: 'Jvalantam iva parvatam’ - meaning, like a mountain of fire. ‘Saṃvartāgni' meaning the delusive fire which burns up the entire world at the end of a kalpa called Pralayā. As fire She burns up the body. As fire She burns up the needs of the body also. All the emotions, feelings and thoughts exist, so long as they're having a body to work in. When the body itself is burnt, then fear, lust, anger, greed, delusion, pride, envy, ego etc. can rest. At the Maṇipūra cakra the devotee offers his body as naivedya to that all engulfing fire of Devi. At the Devīgītā it is said: ‘The devas saw Devi as having for Her food, all the people’. This statement refers to the yogic processes of cutting the Viṣṇugranthi. Having burnt the body at the Maṇipūra cakra, the smoke which comes out of the body consists of the emotions, feelings and thoughts.
