Brahmana, Kshtriya, Vaishya, Shudra (the four castes of Hindu society) is a thought born of illusion. Grihasta, Vanaprastha, Sannyasa (three of the four stages of life as defined by Hinduism) is an illusory thought. Hindu, Muslim, Christian, Jew – is an illusory thought. Religion, tradition, customs, sect (or Path) – all these are illusory thoughts. Men who have been caught in the chains of this bondage are so much worried that they are unable to understand reality. All these bondages are not real. All of them are artificial, illusory, pertaining to thought, and fictitious.
