Bhagavad Gita · 6.47

योगिनामपि सर्वेषां मद्गतेनान्तरात्मना।श्रद्धावान्भजते यो मां स मे युक्ततमो मतः॥

yoginām api sarveṣhāṁ mad-gatenāntar-ātmanā śhraddhāvān bhajate yo māṁ sa me yuktatamo mataḥ

And of all yogis, the one who worships Me with great faith, with the inner self absorbed in Me — that person is the most intimately united with Me and is the highest of all.

— Bhagavad Gita 6.47
