Bhagavad Gita · Chapter 12: The Path of Devotion
Bhagavad Gita 12.17
यो न हृष्यति न द्वेष्टि न शोचति न काङ्क्षति ।
शुभाशुभपरित्यागी भक्तिमान्यः स मे प्रियः ॥
yo na hṛṣyati na dveṣṭi na śocati na kāṅkṣati | śubhāśubhaparityāgī bhaktimānyaḥ sa me priyaḥ ||
One who neither rejoices nor hates, who neither grieves nor craves, who has let go of both good and bad, and who is full of devotion, is dear to me.
Modern context
Neither elated nor hateful, neither grieving nor craving. These are the four great swings of the emotional life, two toward things and two away. The devotee is not swept along by any of them. 'Let go of both good and bad' does not mean moral indifference. It means letting go of attachment to good and bad outcomes, the endless sorting of events into wins and losses.
