ŚVETĀŚVATARA UPANISHAD · 6.12

एको वशी निष्क्रियाणां बहूणाम् एकं बीजं बहुधा यः करोति ।
तम् आत्मस्थं ये ऽनुपश्यन्ति धीरास् तेषां सुखं शाश्वतं नेतरेषां ॥

eko vaśī niṣkriyāṇāṃ bahūṇām ekaṃ bījaṃ bahudhā yaḥ karoti ।
tam ātmasthaṃ ye ’nupaśyanti dhīrās teṣāṃ sukhaṃ śāśvataṃ netareṣāṃ ॥

He is the one ruler of many who (seem to act, but really do) not act; he makes the one seed manifold. The wise who perceive him within their self, to them belongs eternal happiness, not to others.
