In plain words
If instead we bathe only the body and then put the same dirty clothes back on, it does not give us much satisfaction. But when, after cleaning the body, we put on spotless clothes, it brings so much cheer. In just that same way, if we keep purity within us while the place outside stays unclean, even a pure heart takes on some impurity. So the whole of Prakṛti is like the garment we wear. They called this “Dhārayatīti dharmaḥ.” When the Prakṛti we wear is pure as well, our life too is made into a pure citta. But today, trusting too that you will keep the camp ground where you are staying, the place you live in, fairly clean, and so make it ready for this tree to take in water; that you will do it wholeheartedly, so as to begin service of this kind; that you will not go out under the force of the thought that this has just been laid down in the camp as some compulsory service, but will take part in that service with Prema; and that through it you will become the object of the Prema of others: blessing you, I bring My talk to a close.
Even when we set out to do service, we must not set out in a hubbub, as in a market. Slowly, two by two, in line, with discipline: you must look on it as teaching discipline to the people who are watching. Take up your own things and join in this service silently, in line. Rise, and go four by four.
