In plain words
If the Manas is impure, the feelings too become impure
Now inner cleanliness means keeping the Manas and the Buddhi within calm and pure. If one's feelings are impure and full of unrest, one cannot enjoy Śānti. One cannot reach happiness. If the Manas is impure, the feelings become impure. To keep the Manas from being polluted, one has to consider the circumstances and conduct of others well and with discernment, and decide on the proper path. Neither haste nor imitation is good. We must look to the decision of our own heart with wisdom and inquiry, and must not follow something merely because the other man thinks it attractive. Imitation is base and weak. It is bound up with ignorance. It is the effect of avidyā. It is the mark of a sheep. Born as men and passing as educated, we must not soil our Manas by following the Manas of others like sheep or by listening to the words of others. Many may be personal matters. Or they may be bound up with mutual hatred. Why should we follow such ideas of others? We must not yoke our ideas to the ideas of others. We must not give up our purity, our faith and our experience. Belief has no reasons. It goes with each one's own feeling. One must not fall into wickedness through anger, hatred, envy and the like. Students must have broad ideas. The principle of gratitude must enter into them. Only then can they become fit for the highest leadership. Such people alone society too will respect. Selfish ideas and narrow ideas must be pushed aside.
