To satisfy what desire, or for what purpose should the knower of the Truth care for his body, when he knows himself in his own true nature of indivisible bliss. The fruit gained by the successful man, liberated here and now, is the enjoyment in himself of the experience of being and bliss within and without. The fruit of dispassion is understanding, the fruit of understanding is imperturbability, and the fruit of the experience of bliss within is peace. This is the fruit of imperturbability. If the successive stages do not occur it means that the previous ones were ineffective.
Tranquillity is the supreme satisfaction, leading to incomparable bliss.
The fruit of insight referred to is feeling no disquiet at the experience of suffering. The fruit of knowledge should be the turning away from the unreal, while turning towards the unreal is seen to be the fruit of ignorance. This can be seen in the case of some-one who recognises or does not recognise things like a mirage. When there is no upsurge of desire for goods, that is the summit of dispassion. When there is no longer any occurrence of the self-identification with the doer, that is the summit of understanding, and when there is no more arising of latent mental activity, that is the summit of equanimity.
