A jnani is one who has realized the truth of the Self through Vedanta. Outwardly ordinary, inwardly free, the jnani abides in unshakable knowledge: “I am Brahman.”
The purusharthas are the four goals of human life: artha (security), kama (pleasure), dharma (virtue), and moksha (liberation). Vedanta teaches that moksha is the highest and ultimate aim.
