From the Bhagavad Gita verses 29-31

The yogi sees all beings existing in Me and he sees Me existing in all beings. He sees all with equal vision.
A yogi who sees Me everywhere and sees everything in Me, never loses Me nor do I lose him.
A yogi who worships me knowing Me to be the Super Soul within all living beings lives in Me always.

Commentary: The proficient student of mystical reality, the wise, “the yogi” sees the Creator everywhere and in all things. In the plant, even a simple rock, the yogi sees the same Creator both within the object and the object within the Creator. There is no distinction between subject and object. There is no duality. Any duality is only temporary and is therefore less true. From the perspective of what is true eternally, there is only Interbeing.
