In plain words
In Bhāratīya tradition the fruit of karma never fails. The faith of the Bhāratīyas is four kinds of faith. To believe in the fruit of karma is their very first faith. To believe in the principle of the Avatāra is their second faith. That the return of whatever we do will not fail is the third faith. And the fourth: there is a deep faith that in this world, in every matter, there is a certain kind of sacredness. Through these three, purity, Praśānti and perseverance, we can achieve these four. We must achieve the principle of these three well and firmly. So the young men who are students must enter this sacred path from now on, and we must try to enjoy enjoyments joined with sacrifice. We must not long for enjoyment joined with disease. Sacrifice. Sacrifice. Sacrifice alone is the enjoyment we have. I have said it many times. Na karmaṇā na prajayā dhanena tyāgenaike amṛtatvam ānaśuḥ. If we do not let go again of the air we have breathed in, will it bring us good, or harm? The lungs will be damaged. If we do not pass out again the food we have taken, is this a help or a harm? Sacrifice? Enjoyment? No. It turns into disease. The stomach will be ruined. So, just as whatever we take in we must let go, in the same way we must keep giving up the wealth we have earned. What is our wealth? The wealth of Jñāna. The wealth of learning, the wealth of youth, the wealth of Ānanda: all these are wealth for us. We have earned the wealth of learning; we must sacrifice it in teaching that learning to others. Through that sacrifice our learning is nourished and grows still more. If we do not teach it, our learning sinks to the bottom. The more you go on sacrificing, the more it grows. We must not think that we are doing a favour to someone. We are doing a favour to ourselves. When we give this teaching to others, the power of that teaching grows in us day by day.
Students! We look only at our life growing.
