In plain words
What must be given up is not outer sacrifice but inner sacrifice
Mokṣa means release. All beings who have taken an embodiment are always seeking release from one state or another. So every jīva is a seeker of liberation. Every human being must become a ‘tyāgī’, one who gives up. This is the final truth. No one who leaves the body takes even a handful of earth with him. One who does not give up with understanding, Prakṛti teaches by force to give up. It is better to learn to give up before that happens. Such a one alone is blessed. Sacrifice is the second virtue of Vidyā. If you pour out the water in a pot, the space that was room in the pot disappears. Space itself becomes plain. In the same way, if ‘identification with things that are not the Ātma’ is given up, one stands as the Ātma, in the form of Mukti itself. But what must be given up is not outer sacrifice; it is inner sacrifice. Many think that sacrifice means giving away money and land, or having yajñas, yāgas and other rites performed, or leaving house and home, wife and children and going to the forest: such acts they take to be ‘sacrifice’. Sacrifice does not mean such weak acts. Giving these up is not so hard either. If you set your mind to it, these things can easily be done and given up.
