Bhagwad Gita
Chapter 11, Verse 48
न वेदयज्ञाध्ययनैर्न दानै
र्न च क्रियाभिर्न तपोभिरुग्रैः।
एवंरूपः शक्य अहं नृलोके
द्रष्टुं त्वदन्येन कुरुप्रवीर।।11.48।।
O best of the Kuru warriors, no one before you has ever seen this universal form of Mine, for neither by studying the Vedas, nor by performing sacrifices, nor by charities or similar activities can this form be seen. Only you have seen this.
