SEVENTH BRÂHMANA
1. 1. Then Uddâlaka Âruni asked. 'Yâgñavalkya,' he said, 'we dwelt among the Madras in the houses of Patañkala Kâpya, studying the sacrifice. His wife was possessed of a Gandharva, and we asked him: "Who art thou?" He answered: "I am Kabandha Âtharvana." And he said to Patañkala Kâpya and to (us) students: "Dost thou know, Kâpya, that thread by which this world and the other world, and all beings are strung together?" And Patañkala Kâpya replied: "I do not know it, Sir." He said again to Patañkala Kâpya and to (us) students: "Dost thou know, Kâpya, that puller (ruler) within (antaryâmin), who within pulls (rules) this world and the other world and all beings?" And Patañkala Kâpya replied: "I do not know it, Sir." He said again to Patañkala Kâpya and to (us) students: "He, O Kâpya, who knows that thread and him who pulls (it) within, he knows Brahman, he knows the worlds, he knows the Devas, he knows the Vedas, he knows the Bhûtas (creatures), he knows the Self, he knows everything." Thus did he (the Gandharva) say to them, and I know it. If thou, O Yâgñavalkya, without knowing that string and the puller within, drivest away those Brahma-cows (the cows offered as a prize to him who best knows Brahman), thy head will fall off.'
Yâgñavalkya said: 'O Gautama, I believe I know that thread and the puller within.' The other said: 'Anybody may say, I know, I know. Tell what thou knowest.'
