Bhagavad Gita 9.5
Nevertheless, they do not consciously abide in Me. Such is My Divine Sovereignty that, though I, the Supreme Self, am the cause and upholder of all, yet I remain outside.
न च मत्स्थानि भूतानि पश्य मे योगमैश्वरम्।
भूतभृन्न च भूतस्थो ममात्मा भूतभावनः॥na ca matsthāni bhūtāni paśya me yogamaiśvaram|
bhūtabhṛnna ca bhūtastho mamātmā bhūtabhāvanaḥ||
