Varna and Caste System
Varna is the nature of an individual based on gunas(Sattva, Rajas, and Tamas) and activities in which one is interested in a particular kind of job or occupation to earn a living, and Caste means a lineage of an individual about which job or profession his/her very early ancestors used or made to do as a family profession. The whole varna was made keeping in view the dharma that one had to follow. Varna was never considered by birth if we go through the following instances of our great literature. In Srimad Bhagavad Gita Chapter IV Verse 13, Lord Krishna clearly states that the four Varnas are based on their work and their basic nature and not related to birth at all. "chātur-varṇyaṁ mayā sṛiṣhṭaṁ guṇa-karma-vibhāgaśhaḥ tasya kartāram api māṁ viddhyakartāram avyayam" The four varnas have been created by Me through a classification of the gunas and activities. Even though I am the creator of this system, still know Me to be the non-doer and eternal. Lord Krishn
