Bhagavad Gita 8.22
O Arjuna! That Highest God, in Whom all beings abide, and Who pervades the entire universe, is reached only by wholehearted devotion. *He is the one who determines the course of worldly events and the destiny of all living beings.*
पुरुषः स परः पार्थ भक्त्या लभ्यस्त्वनन्यया।
यस्यान्तःस्थानि भूतानि येन सर्वमिदं ततम्॥puruṣaḥ sa paraḥ pārtha bhaktyā labhyastvananyayā|
yasyāntaḥsthāni bhūtāni yena sarvamidaṃ tatam||
