In plain words
We must keep them within just the bounds within which they ought to be kept. We must keep our acquaintance within limits. Once this limit is crossed, the boundary is overrun. Then it becomes very hard for us to control it again.
Develop Good Qualities
Man must protect his humanity at least to some extent. Because man today cannot protect human values, he is falling into so many kinds of evil conduct. If a man is born a man and the human qualities do not enter into him, what further use is there in his being born a man? So, since we are born as men, we must foster the human qualities. The very first is Satya. We must safeguard this Satya. The second is Dharma. We must practise Dharma. With this in view, the Veda said, ‘Satyaṃ vada, dharmaṃ cara.’ After these two comes Śānti. Śānti is a chief ornament for man. Without this Śānti there is no happiness at all. So Tyāgarāja said, ‘Without Śānti there is no happiness.’ For everything, Prema is the chief breath of life. So we must take up these four, Satya, Dharma, Śānti and Prema, as the human qualities. Through them we must go on developing the human qualities. Man today appears as a man in form, but he is falling behind in practising the human qualities. In form he is a man; in conduct he is a demon. While we have the human form, we must safeguard the human qualities. In man today the human qualities are not to be seen at all. In some situations here and there, in some places here and there, they appear now and then as a show. This is not right. Every human quality must spring from our heart. This is no exhibition, to be put on display. These human qualities are to be an example, not an exhibition. We must put them into practice and let them enter our blood. We must make them run through us from the toe-nails to the crown of the head. Whatever word we speak, whatever work we do, whatever thought we think, we must reflect well on the human qualities.
