Almost all our suffering is caused by our not having the power of detachment. So along with the development of concentration, we must develop the power of detachment. We must learn not only to attach the mind to one thing exclusively, but also to detach it at a moment’s notice and place it upon something else. These two should be developed together to make it (the mind) safe. (CW, 6:38)
To restrain the indriyas (organs) from going toward the objects of the senses, to control them and bring them under the guidance of the will, is the very central virtue in religious culture. (CW, 3:66)
All actions, internal and external, occur when the mind joins itself to certain centres (centers), called the organs. Willingly or unwillingly it is drawn to join itself to the centres (center), and that is why people do foolish deeds and feel miserable, which, if the mind were under control, they would not do. — What would be the result of controlling the mind? It then would not join itself to the centres (center) of perception, and, naturally, feeling and willing would be under control. (CW, 1:171)
The flame of a lamp sheltered from the wind does not flicker. This is the comparison used to describe a Yogi’s mind that is well under control and united with the ‘Atman. (6.19)
From whatsoever reason this wavering and fickle mind wanders away, it should be curbed and brought to abide in the Self alone. (6.26)
Meditation: You must keep the mind fixed on one object, like an unbroken stream of oil.
The ordinary man’s mind is scattered on different objects, and at the time of meditation, too, the mind is at first apt to wander. But let any desire whatever arise in the mind, you must sit calmly and watch what sort of ideas are coming. By continuing to watch in that way, the mind becomes calm, and there are no more thought-waves in it. (CW, 7:253-54)
