FAQs
It distinguishes the witnessing Self (kṣetrajña) from the sense of doership: what appears as ‘activity’ is karma-born and belongs to saṃsāra, which is described as lacking true essence—pointing the seeker toward detachment and liberation.
By showing that worldly agency is karma-driven and unstable, it supports bhakti as surrender: offering actions to Bhagavan and loosening identification with doership, which steadies the mind for remembrance and devotion.
No specific Vedanga (like Vyākaraṇa, Jyotiṣa, or Kalpa) is taught in this verse; it is primarily a Moksha-Dharma/Vedāntic point about karma-born agency and the kṣetrajña (Self).
