The verse 3.7.2 of Brihadaranyaka upanishad says :
He said, 'Vayu, O Gautama, is that Sutra. Through this Sutra or Vayu this and the next life and all beings are held together. Therefore, O Gautama, when a man dies, they say that his limbs have been loosened, for they are held together, O Gautama, by the Sutra or Vayu'.'Quite so, Yajnavalkya. Now describe the Internal Ruler'.
It says vAyu binds all being together indicating vAyu a Cosmic Spirit or God.
Vayu is called Brahman in Shanti Mantra - Namo brahmane namaste vaayo twameva pratyaksham Brahmaasi.
Sri Krishna says in BG 7.7 as follows:
मत्त: परतरं नान्यत्किञ्चिदस्ति धनञ्जय | मयि सर्वमिदं प्रोतं सूत्रे मणिगणा इव ||
There is nothing higher than myself, O Arjun. Everything rests in me, as beads strung on a thread.
My question is whether verse 3.7.2 of Brihadaranyaka upanishad, a forerunner to Sri Krishna's statement in verse 7.7 of BG?
