Bhagwad Gita
Chapter 11, Verse 7
इहैकस्थं जगत्कृत्स्नं पश्याद्य सचराचरम्।
मम देहे गुडाकेश यच्चान्यद्द्रष्टुमिच्छसि।।11.7।।
Whatever you wish to see can be seen all at once in this body. This universal form can show you all that you now desire, as well as whatever you may desire in the future. Everything is here completely.
