Bhagavad Gita · Chapter 11: The Vision of the Cosmic Form
Bhagavad Gita 11.40
नमः पुरस्तादथ पृष्ठतस्ते
नमोऽस्तु ते सर्वत एव सर्व ।
अनन्तवीर्यामितविक्रमस्त्वं
सर्वं समाप्नोषि ततोऽसि सर्वः ॥
namaḥ purastādatha pṛṣṭhataste namo'stu te sarvata eva sarva | anantavīryāmitavikramastvaṃ sarvaṃ samāpnoṣi tato'si sarvaḥ ||
Salutations to you from in front and from behind; salutations to you from every side, O All. Infinite in power and immeasurable in might, you pervade everything, and so you are everything.
Modern context
Salutations from the front, from behind, from every side. Arjuna turns in every direction to bow, because there is no direction where the divine is not. And then the conclusion: you pervade everything, therefore you are everything. If we took this seriously in daily life, every direction we faced would be a direction for reverence.
