Bhagavad Gita · Chapter 14: The Three Qualities of Nature
Bhagavad Gita 14.20
गुणानेतानतीत्य त्रीन्देही देहसमुद्भवान् ।
जन्ममृत्युजरादुःखैर्विमुक्तोऽमृतमश्नुते ॥
guṇānetānatītya trīndehī dehasamudbhavān | janmamṛtyujarāduḥkhairvimukto'mṛtamaśnute ||
Going beyond these three qualities, from which the body arises, the embodied self is freed from birth, death, old age, and sorrow, and attains immortality.
Modern context
Going beyond all three gunas brings freedom from birth, death, old age and sorrow. Notice that even sattva has to be transcended. The goal is not to be the best kind of personality but to be free from being defined by personality at all. This is a gentle but radical teaching. Even our virtues, if we cling to them, can become a subtle prison.
