Acharya Prashant explains that the concept of the seven chakras is purely symbolic and not physical. He clarifies that 'chakra' refers to the various levels or circles of the mind in which an individual remains trapped. For instance, the lowest chakra, Muladhara, represents being stuck in basic instincts and lust. The spiritual journey involves rising through these symbolic levels to eventually attain liberation from all circles, often described as the opening of the thousand-petaled lotus. He emphasizes that these are metaphors used to communicate spiritual progress and do not exist as literal entities within the body.
