There are three types of men: the multi-centred, the uni-centred and the non-centred. The first group who allow their senses, mind and intelligence to wander where they will is a very populous group. So also is the third group, which comprises people who flit from one object to another, hop around from one thing to another in listless flippancy. For earning concentration and single-centredness characteristic of the second group, the festival of Shivaratri is very propitious. The Bhajans and the ceaseless flow of kirtana and Namasmarana on this occasion help in the attainment of single-centredness. (SSS Vol.10, pp. 157-158)

There are four types of people. The anger of a person who is of a sattvika nature will be very short-lived; it recedes immediately. The Gita has declared such a one as a great soul. The second type will have this anger for a number of minutes, but it will soon fade away. The third category of person will have - this anger continuously, all day long. Thc one in the lowest category will have this anger for all his life. The Gita teacher has told this in another way also. The anger of a good person is like writing on water; it is not at all permanent. The anger of the second category of person is like writing on sand, it will be washed away, one moment or another. The third type of person’s anger is something like writing on stone. Over a long period of time it too will be eroded away. But the anger of the fourth type of person is like writing in. a steel plate; it will never go away unless you melt it and cast it anew. Only when you put it into fire will it get destroyed, only through an intense transformation will it be possible to change it. (DBG, p. 86/87)
