We often read it and sometimes pretend also to believe it but ask yourself once, do we really follow it?  

‘’Casteism is racism and India should stop it’’
Do we really don’t discriminate people on the basis of their caste?

Casteism doesn’t lies in division of categories but it is a peril to human unity. It fragments people into groups and impedes in the growth of a nation. But do you think it’s that easy to liquidate the concept from the society where these myths have been embarked in our psyche?
Who initiated Casteism? Is it Man-made, so we are actually following a man-made thing blindly without using our own brains? Some says it’s in shashtras, then is it made by God? Is it mentioned there that we should discriminate people against caste?

To explain further, this is what in Bhagavad-gita (4.13) Lord Krishna says, "According to the three modes of material nature and the work ascribed to them, the four divisions of human society were created by Me." Then he continues, "Brahmanas, kshatriyas, Vaidhyas and Shudras are distinguished by their qualities of work in accordance with the modes of nature." Herein we can see that there is no such declaration that a man has to be discriminated on the basis of caste throughout. It was only meant to bring ease in socio-economic functionality. They are ascertained by their qualities of work and nothing else. Furthermore, "By following his qualities of work, every man can become perfect. . . By worship of the Lord, who is the source of all beings and who is all-pervading, man can, in the performance of his own duty [or occupation], attain perfection." (Bg.18.45-6)

Herein we conclude that these divisions were meant with good intentions which has eventually wrapped up by negative cloth of discrimination and Casteism by the society.  Therefore, the persons who used to be the informer of deity and are intellectuals were considered as Brahmins, those who worked as warriors on fields were considered as kshatriyas, those who used to serve business or administrative work were belong to Vaidhyas and finally those who prefer to serve society through physical labour were considered as Shudras.
But it’s not mentioned anywhere that Shudra’s kin will always be Shudra even if his mode of work is different. That is the one thing that clings to my mind that why do we stress on caste so much when it really doesn’t make any sense in present times and doesn’t matter at all. Not only this, a Shudra’s kin can never be allowed to worship or work like a Brahmin even if he could be the best Brahmin ever by shashtras, because it’s the stereotypical mind and wrong concept of our society who will always be against it. Even if you are from Brahmin family but you do business, you won’t be considered as Vaidyas, but actually you are.
Therefore before judging the caste of next person sitting beside you, think for yourself once...are you a Brahmin or Shudra? Because its actual meaning lies on the nature of work you do not what your father used to do. Theses heavy words originated for an easy social functionality but not to divide or fragment people’s unity.

Just contemplate on it.
