BG Chap 18 - Tyāga in the mode of goodness
Tyāga in which obligatory actions are performed out of duty, without sense of doership and desire for results, is in the mode of goodness, since such awareness is in sattva guṇa. A man working in Kṛṣṇa consciousness in a factory does not associate himself with the work of the factory, nor with the workers of the factory. He simply works for Kṛṣṇa. And when he gives up the result for Kṛṣṇa, he is acting transcendentally. It is understood here that the result of renouncing the fruits and not renouncing the action in sāttvika tyāga is knowledge.
