Kṛṣṇa summarizes the wide variety of sacrifices approved by the scriptures. He says they are all ‘vitatā brahmaṇo mukhe’—they are all ways to reach the Divine. More importantly, He tells Arjuna to know that all these sacrifices are ‘karma-jān’, or born of work. This is a crucial point for Arjuna: spirituality is not a state of laziness or mental dreaming. It involves action. Whether it is the action of studying, the action of giving charity, or the action of controlling the breath, the soul must be active. The soul is not inert; it is dynamic. “Knowing this, you will be liberated.” Kṛṣṇa is teaching Arjuna that he doesn’t have to choose between work and freedom. Work *is* the path to freedom if it is done as a sacrifice. By understanding that his participation in the war is his specifically ordained ‘yajña’, Arjuna can fight with total commitment and yet remain perfectly free from all bondage.
