Yagnavalkya said: `Vayu (air) is that thread, O Gautama. By air, as by a thread, O Gautama, this world and the other world, and all creatures are strung together. Therefore, O Gautama, people say of a dead person that his limbs have become unstrung; for by air, as by a thread, O Gautama, they were strung together.' The other said: `So it is, O Yagnavalkya. Tell now (who is) the puller within.'
