तस्मा॑द्य॒ज्ञात्स॑र्व॒हुत॒ ऋचः॒ सामा॑नि जज्ञिरे ।
छन्दां॑सि जज्ञिरे॒ तस्मा॒द्यजु॒स्तस्मा॑दजायत ॥९॥

The one who has no death, who is ever knowledgeable, who does not have even an iota of ignorance, who is always in bliss, is called Sarvahuth (सर्वहुत). That means "He is the one" with all capabilities. From such a Parabrahma (परब्रह्मन्), the Vedas - Rigvēda, Samavēda were born. From that Parabrahma, Atharvavēda was born. From that Parabrahma Yajurvēda was born.
