In plain words
No man is enjoying peace and security. The reason: he is filled with bad saṅkalpas alone. So we must put bad saṅkalpas far away. This life is very sacred. We must develop the faith that whatever is done to whomever comes back to us. Only when we have such faith will we keep from doing harm to others. If we say, ‘We will just do now what has to be done, and see when its fruit comes,’ that turns into tāmasa. It takes shape as a form of rajoguṇa. The very birthplace of desire and anger is rajoguṇa. This rajoguṇa destroys man. Through pure, sāttvic saṅkalpas we must become sāttvic men. This is true education. Only when we learn this education do we take up right paths in the learning of the Ātma and in worldly learning alike. The union of learning and tapas is true divinity. What is tapas? To bring these three into unity is itself tapas. Merely going to the forest, sitting in some cave and dwelling on God is not tapas. To make the three guṇas one and lead them into a divine feeling is tapas. If the three guṇas are not made one in that way, it turns into tamas. So we must not be embodiments of tamas; we must be embodiments of tapas. Without ceasing we must practise the tapa of good saṅkalpas. The very heat of those good saṅkalpas must turn into tapas.
Manas is a gathering of saṅkalpas
We must hold saṅkalpas to be as dear as life. We must shape them into good saṅkalpas. We must not think of doing harm or ill to anyone at any time. That is why they said, ‘Harm no one, or you will come to harm.’ If we keep wishing evil to others, that evil befalls us too. If we strike a ball against a wall, it comes back toward us.
