In plain words
Spiritual power too grows through this silence. Talking too much sets up a nervousness in man. Because of it he keeps losing even the power of discernment that knows what to say and what not to say. The less we talk, the more we can take part in service.
Now, in this service we can also develop friendship of many kinds. What is this friendship? It is not merely greeting one another with "Hello, hello." At all times, in all circumstances, in every field, each one must set about working in unity. If we look about the world and enquire, such a spirit of friendship is nowhere to be seen. They spoke of suhṛt-bhāva. Suhṛt means a good friend. Who is that? In this world, God alone is the good friend. Father, mother, wife, husband, son: whoever it may be, each loves others with some self-interest and private gain kept in view, more or less. The one who loves with no selfishness of any kind, with no self-interest of any kind, is God alone. He expects no reward of any kind. He receives nothing from anyone. Giving alone is His aim. Receiving is not His aim. When we wish to attain such divinity, we must cultivate right conduct and right qualities.
If we enquire where God is, we get a fine chance to recognise it for ourselves. If someone asks your friend, "Where are you?", he may say, "I am in such-and-such a house on such-and-such a road." He may give the address of the house he lives in. But who is it that lives there? Only the upādhi lives there. But is he the body itself? Where does he live? He lives in our very heart. That heart is called Prema. In Prema itself every man lives. By Prema itself he does his daily duties. From dawn until he lies down at night, he makes his time worthwhile through Prema alone. So Prema itself is his dwelling. When he finds that true address called Prema, man can shape himself into an ideal man through right behaviour and right qualities. Through words and deeds, through conduct, through behaviour, we can nourish character to some extent.
