It is said that once a travelling circus came to a village with a most unique attraction known as the tent of mirrors. Anyone who entered it would see a whole army of their own selves due to the mirrors reflecting back and forth indefinitely. A dog entered this tent, saw an infinite number of dogs that looked like him, was afraid and started barking in fear. A passerby went in to see what was going on. Now when he saw himself in those infinite reflections, he thought to himself – I see myself everywhere, how nice this is!
Shri Krishna says that when we see our “I” as no different from anyone or anything else, when we do not pay attention to the name and form but to the self or aatmaa that is the basis of all name and form, that is the correct way of knowing Purushottama, the foremost person. Any other way of conceptualizing Purushottama or the eternal essence will involve some degree of delusion, some trace of name and form involvement. Worship of Ishvara as a deity with name and form is an essential step in the direction of realizing the Purushottama who is beyond all name and form.
When one reaches this conclusion of one’s spiritual journey, there is nothing else left to be known in this world. Such a person becomes sarvavit, all knowing. He will develop sarvaatma bhaava, he will see himself in everything and everyone. So then, no matter the viewpoint, whatever angle, whatever pursuit he will undertake after this knowledge, it will be in worship of this Purushottama. This is the grand message of the Bhagavad Gita.
