Shankaracharya's commentary, trans. Alladi Mahadeva Sastry (1897)
[1]When the seer beholds not an agent other than the guṇas and knows Him who is higher than the guṇas, he attains to My being.

नान्यं गुणेभ्यः कर्तारं यदा द्रष्टानुपश्यति । गुणेभ्यश् च परं वेत्ति मद्भावं सोऽधिगच्छति ॥
nānyaṃ guṇebhyaḥ kartāraṃ yadā draṣṭānupaśyati | guṇebhyaś ca paraṃ vetti mad-bhāvaṃ so'dhigacchati ||
"When the seer sees only guṇas as agents and knows what is beyond them — he attains My being."
