Acharya Prashant comments on a quote by Ramana Maharshi regarding one's duty. He begins by identifying the keywords in the quote: 'duty', 'work', and 'requirement'. He then questions whether the word 'duty' applies to machines or animals. He explains that while machines and animals are always doing something, their actions are based on their design or instinct. One does not scold a machine for neglecting its duty. Similarly, the concept of duty does not apply to animals; they do a lot but never perform duties. The speaker asserts that what distinguishes man from animals is his unique consciousness, which seeks expansion, understanding, and liberation. Therefore, it is this very consciousness that gives rise to the concept of duty for human beings. Man's central duty is to take his consciousness to its pinnacle. This central duty, which is liberation, becomes the touchstone to test all other so-called duties. Any action that leads towards liberation is a real duty, and anything that does not is a false, junk duty that drains one's precious energy and time. Fulfilling these false duties is a waste of life and an ignorance of one's real duty. He uses the analogy of an airplane needing 100% of its fuel to complete its journey; 99.9% is not enough and will result in a crash. Similarly, one's real duty demands 100% of their being, time, and resources, leaving no space for frivolous duties. One cannot fulfill both the real duty and the false ones. The speaker equates this real duty with Dharma, stating that life itself is a duty. We exist to fulfill our central duty, which is to live for Dharma—Truth and Liberation. This is what Shri Krishna explains to Arjun: he must fight because it is his duty to establish Truth. To live for something real is the real duty.
