Bhagavad Gita 9.6यथाऽऽकाशस्थितो नित्यं वायुः सर्वत्रगो महान्।तथा सर्वाणि भूतानि मत्स्थानीत्युपधारय ॥

The Lord gives a beautiful illustration or simile in this verse to explain what He has said in the previous two verses. Just as the wind ever rests in the ether (space) without any contact or attachment, so also all beings and objects rest in Brahman without any attachment or contact at all. These objects cannot produce any effect on It.What sort of relationship is there between Brahman and the objects of this universe Is it Samyoga, Samavaya or Tadatmya Sambandha The relationship of the stick with the drum is Samyaoga Sambandha. Let us assume that there is such a Sambandha (relationship or connection). There cannot be connection between all the parts because Brahman is infinite and the elements are finite. You may say that there is connection of the Ekadesa type. This is also not possible, because there can be such relationship only between objects which possess members or parts like the tree and monkey. (Ekadesa is partial). Brahman has no parts.If you say that there is Samavaya Sambandha between Brahman and the objects or the elements, this is also not possible. The relationship between the attribute and the possessors of that attribute is called Samavaya Sambandha. The relationship between an individual Brahmin and the whole Brahmin caste is also Samavaya Sambandha. The relationship between hand and man, between the leg and the man is also Samavaya Sambandha
