Bhagavad Gita 13.27यावत्सञ्जायते किञ्चित्सत्त्वं स्थावरजङ्गमम्।क्षेत्रक्षेत्रज्ञसंयोगात्तद्विद्धि भरतर्षभ ॥

O Arjuna, remember that whatever is born, unmoving or moving, know thou that to be done to the union between the body and the Self.The knower of the field is like the ether without parts. Therefore, there cannot be a union of the field and the knower of the field through contact of each others parts like the contact of the drum and the stick or a rope and a vessel. There cannot be the inseparable connection between them like the connection that exists between the head and the neck, or the arm and the shoulder, because the field and its knower are not related to each other as cause and effect.Then, what sort of union is there between the field and its knower It is of the nature of mutual superimposition or illusion. This consists in confounding the one with the other as well as their attributes, like the union of a rope with a snake, and motherofpearl with silver, on account of lack of discrimination of their real nature. The attributes of the Self are transferred to the body and vice versa. The insentient body is mistaken for the sentient Self. The activities of the body or Nature are transferred to the silent, actionless Self
