Verse
भक्त्या त्वनन्यया शक्य अहमेवंविधोऽर्जुन ।ज्ञातुं द्रष्टुं च तत्वेन प्रवेष्टुं च परंतप ॥
The Blessed Lord said: The greater Form that thou hast seen is only for the rare highest souls. The gods themselves ever desire to look upon it. Nor can I be seen as thou hast seen Me by Veda or austerities or gifts or sacrifice; it can be seen, known, entered into only by that bhakti which regards, adores and loves Me alone in all things.
Gītā 11·54
