In plain words
However long we travel on this river called life, we must see to it, though, that no water comes into the boat. Put the boat in the water, but never let the water into the boat. Stay in family life. Carry out your duties, but do not torment yourself by keeping them in your Manas. It is only from that that diseases grow. You must be where you ought to be. You must hold this to be only a tool. Do your duty; but do not keep the whole burden in your Manas and fall ill for nothing. So when we want to keep the body in the right condition, food and conduct are most necessary. So, holding this body to be a tool and accepting it as a garment we have put on, we must make the effort to cleanse, from time to time, the dirt that gathers in this garment. The garment we wear gets dirty; what do we do? We give it to the dhobi. What does the dhobi do? He takes away the dirt. What is its natural colour? Its natural colour is white. But through our using it, it turns another colour. We give this garment, changed and full of dirt, to the washerman. The washerman takes away its dirt and brings it back. Through delusion we think that the washerman has made it white and brought it. White is its very nature. The washerman did not give it that anew. The work the washerman did was to remove its dirt. In just the same way, this body we have put on has its own natural colour, its own natural nature. But because we use it against its nature, dirt keeps gathering in it. When you give it to the washerman called thinking of God, Prema for God and dhyāna on God, it becomes pure. God is the washerman. That is, He is the One who purifies your heart. So hand over your heart to God. He Himself will clean it. If instead, without recognising to whom you should give your dirty garment to have it cleaned, you give that garment to the barber, what will he do? So if you want it cleaned, you must give it to the washerman. If you want your heart to become pure, you must hand it over to God alone. No one else can clean it.
