Bhagavad Gita · 11.4

मन्यसे यदि तच्छक्यं मया द्रष्टुमिति प्रभो।योगेश्वर ततो मे त्वं दर्शयात्मानमव्ययम्॥

manyase yadi tach chhakyaṁ mayā draṣhṭum iti prabho yogeśhvara tato me tvaṁ darśhayātmānam avyayam

If you think it possible for me to behold it, O Lord of Yoga, then reveal to me your imperishable self.
