Caste belongs to just the ego.
What is caste, first of all?
It is a kind of division, right? It is a kind of divisionโdivision that says that here is this person who must engage in this kind of occupation and here is this person who must engage in this kind of occupation.
The Upanishad is categorically refuting such a system because such a system exists purely on the basis of body and flesh and bones.
You see, the ego has a greatly vested interest in thinking of superiority and inferiority as belonging to the domain of the body.
In the beginning, the original intention had to be personal, not social. Iโm saying that the comparison originally would not have been between two different persons but actually between two different states of the same person.
You see, what is the entire purpose of spirituality? The purpose is that you must rise from a lower state to a higher state.
Now, this is the beginning of the caste system. The lower state and the higher state exist within the same person, right?
Who is a lowly person? Who keeps thinking of himself as a mere body, just as animals do. Who is a higher or holy person? Who starts seeing that body-identification is at the root of most human suffering.
Caste simply means a gradation. Sometimes, you are at a low point in your consciousness. And if you make efforts, if you pay the right price, if you are determined enough and you act wisely, then you find that you are graduating, evolving, moving. Thatโs the whole point of saying that there are differences. Caste implies difference.
This difference is actually some kind of a ladder that has been shown to you.
You are born a body. Even the so-called Brahmins are born body-identified. In some sense, everybody is born a Shudra because we all are body-identified, and then the possibility to move up the ladder of consciousness is available to everybody irrespective of his or her birth or gender or anything. The one who manages to reach the highest rung of the ladder is a Brahmin because at the highest rung sits Brahman.
