In plain words
So the moment saṅkalpas are born, we must enquire whether they are good or bad. A life that keeps developing bad saṅkalpas in our citta enters a bad path. When we enquire even into each small matter, ‘Is this a harm done to others? Or is it a harm one has done to oneself?’ then it becomes possible to know that truth.
Take one matter: we have decided to invite two friends to a feast. This feast is not for those two alone. We too eat the feast made for others. But we think of it as made for others. We too enjoy the feast that is made for others. In the same way, the bad saṅkalpas we think up for others come into our own experience and torment us too. For example, we resolve that the country must be ruined. Along with the country's ruin, we who live in that country must be ruined too. Though the saṅkalpa is one, it takes on many forms, and many shapes arise from it. A saṅkalpa came: to hold a tea party. To fulfil that saṅkalpa, at once plates, saucers, tea, milk, biscuits, tables and chairs all appear. How many things arise from one saṅkalpa! One saṅkalpa takes shape in many ways, and goes on into many kinds of action. So it is essential to recognise the power of saṅkalpas well.
Dharma must lie within everything
We have been born as human beings. So in human beings it is good saṅkalpas alone that must be developed.
