The Upanishads reveal that we are limitless, the sought is enshrined in the seeker, Tat tvam asi. We only become a victim of our notion of being limited because we erroneously superimpose limitations of our body-mind-sense on the limitless Consciousness that enlivens it. Consciousness is all there is; and one is that non-dual Consciousness.
If one is already limitless, it can only be gained by knowledge and not by any action; ‘naasti akritah kriten’, warn the Vedas. Then what is the utility of work? Carried out with an attitude of dedication to the Divine with no attachments to the result, the work purifies one’s inner instrument, the mind.
A pure mind realises the reality in no time. In the Bhagwad Gita too, Krishn exhorts Arjun to be a karma yogi, elucidating the merits of action done with the spirit of renunciation and duty. Such an action paves the way to the wellspring of wisdom and well-being within.
