Bhagavad Gita · 14.19

नान्यं गुणेभ्यः कर्तारं यदा द्रष्टानुपश्यति।गुणेभ्यश्च परं वेत्ति मद्भावं सोऽधिगच्छति॥

nānyaṁ guṇebhyaḥ kartāraṁ yadā draṣhṭānupaśhyati guṇebhyaśh cha paraṁ vetti mad-bhāvaṁ so 'dhigachchhati

When the seer perceives no doer other than the gunas and knows that which is beyond the gunas, that person attains my divine nature.
