...from the scientific point of view.
The verse also has its own social significance.
Let's comprehend. The word Varna is made of root word 'Var' which has many meanings-to choose, to demand, to desire etc. It is evident from this that the word Varna means,"to choose the desired work or thing". To assimilate Varna with caste is utterly irrational &sheer ignorance.
Above shloka translates to,
'Segregating the deeds based on properties, I composed four varna, ie 4 types of karma, with a freedom to choose are composed by me.' It's very important to note here that the division of Karma is based on qualities &there is a freedom to choose yours.
Hence, the word varna cannot be associated with caste as it's not based on birth rather its based on the Karma and there is also the option to choose your karma. Brahmin, kshatriyas,vaishya & shudras, these all words are qualitative nouns.
Apparently,this is the delusion created by some anti india forces, so that Hindus keep on fighting with each other on the name of caste & could not be united ever. This is a hindrance intentionally created by these anti nationals in the path of our society's collective progress.
Whereas, casteism has nothing to do with the Sanatan Dharma. Ours is the only Dharma where the God itself gives you the choice of changing your Karma. Therefore, a Brahmin can become Shudra by his karma and vice versa.
शूद्रो ब्राह्मणतामेति ब्राह्मणश्चैति शूद्रतां ।
क्षत्रियाज जातमेवं तु विद्याद वैश्यात तथैव च ।। (Manusmriti 10.65)
It translates,"The Sudra can attain the position of the Brahmana & the Brahmana can sink to the position of Sudra; same thing also applies to Kshatriya and Vaisya."
जन्मना जायते शूद्र: संस्कारात द्विज उच्यते
शापानुग्रहसामर्थ्यम तथा क्रोध: प्रसन्नता ।।
(Skand Puran Ch 239, 31:34)
It translates,"Every man is born as shudra during his birth.But by gaining wisdom,knowledge & dharma, he is twice born in same life &such people r known as Dwija...
...and they can get qualities of Brahmins. Some of the best examples of dwija are Valmiki, Siddhartha Gautama etc.
दिष्टपुत्रस्तु नाभागो वैश्यात्तमगामत्तसमा द्वलघाना: पुत्रोभवत।
पृषद्रषतु मनुपुत्रों गुरुगोवधाछूद्रत्त्मागमत।।
(Vishnu Puran verse 16:17)
It translates," B'coz of their Karma and level of wisdom, son of king Dishta became Vaishya from Kshatriya. And, Purushadra, who was son of King Manu became Shudra from Kshatriya."
From the above evidences, it can be easily concluded that, the Varna of a person does not belongs to him by birth. Rather he can make his Varna, whatever he wants to make.
The Varna System, very easily fits even in the present times as the Karma of a society....
...can today also be characterized into 4 types ie intellectual, defence, business and service work. Service work is not meant to serve anyone's feet, but to do social work to help or facilitate society.
The people who don't have any knowledge about our Holy scriptures are very easy to misled and those people are particularly the target of those anti social, anti Hindu and anti india elements who want to divide us and want us to keep fighting with each other in the name of caste.
Bcoz dat's their motive,to nip Hindu collective voice in the bud &keep us from progressing as a society&as a nation.Lastly,I want to conclude by sayin dat a civilization unaware of its own scriptures,history &heritage can't be saved for long.
Please, don't let them destroy us.
