Verse
पुरुषः स परः पार्थ भक्त्या लभ्यस्त्वनन्यया ।यस्यान्तःस्थानि भूतानि येन सर्वमिदं ततम् ॥
puruṣaḥ sa paraḥ pārtha bhaktyā labhyastvananyayāyasyāntaḥsthāni bhūtāni yena sarvamidaṃ tatam
But that supreme Purusha has to be won by a bhakti which turns to him alone in whom all beings exist and by whom all this world has been extended in space.
Gītā 8·22
