And now the threefold kinds of pleasure hear thou from Me, O bull of the Bharatas. That in which one by self-discipline rejoiceth and which putteth an end to pain; which at first is as poison but in the end is as nectar; that pleasure is said to be sattwic, born of the satisfaction of the higher mind and spirit.
Gītā 18·37This happiness does not depend on outward things, but on ourselves alone and on the flowering of what is best and most inward within us. But it is not at first our normal possession; it has to be conquered by self-discipline, a labour of the soul, a high and arduous endeavour. At first this means much loss of habitual pleasure, much suffering and struggle, a poison born of the churning of our nature, a painful conflict of forces, much revolt and opposition to the change due to the ill-will of the members or the insistence of vital movements, but in the end the nectar of immortality rises in the place of this bitterness and as we climb to the higher spiritual nature we come to the end of sorrow, the euthanasia of grief and pain. That is the surpassing happiness which descends upon us at the point or line of culmination of the sattwic discipline.
