Bhagavad Gita Chapter 3, Verse 10

सहयज्ञाः प्रजाः सृष्ट्वा पुरोवाच प्रजापतिः | अनेन प्रसविष्यध्वमेष वोऽस्त्विष्टकामधुक् ||

saha-yajñāḥ prajāḥ sṛṣṭvā purovāca prajāpatiḥ anena prasaviṣyadhvam eṣa vo 'stv iṣṭa-kāma-dhuk

In the beginning of creation, the Lord of all creatures sent forth generations of men and demigods, along with sacrifices for Vishnu, and blessed them by saying, 'Be thou happy by this yajna because its performance will bestow upon you everything desirable for living happily and achieving liberation.'

Krishna reveals the cosmic blueprint: at creation's beginning, the Lord established humanity with yajna—the principle of mutual contribution. This isn't just spiritual advice; it's how reality works. Prosperity flows from giving, not taking. When you contribute selflessly, the universe supports you in return. It's not transactional but ecological—like a forest where each organism gives and receives, creating abundance. Yajna isn't merely ritual; it's the operating system of existence itself.
