I think you missed my point completely. I will reiterate that if you keep making it seem like the Varna System is only for getting qualified people then I will keep telling you that is nothing special. I heard about some other aspects of it that were more about equality. You can keep focusing on the aspect of being qualified but I cannot see possibly how there is anything unique in this. They should focus on equality as in not oppressing others. I already know that from what others have said that the Caste System by birth is not Varna System... I know this. I am just saying that the Varna System, if it originated truly from God, was most likely to bring equality in classes such that they spread wealth. That was the SYSTEM. I don't think the main point was to appoint qualified individuals, as this was possibly already structure earlier on in society. Maybe it reiterated it. Like with most religions its teachings got exploited by others in what we know now as Caste System. It maybe the Varna System was a stepping stone in improving society structure, but I would not extend so far as to state it created it.
Varna System, was designed for an individual to progress
spiritually. That is at the heart of Varna System. All others are at the peripheral level.
The four Varnas were created to give individuals the chance to utilize their qualities and merits in the service of society and progress spiritually. The four Ashramas were designed for members of all caste to advance in their realization of God and to advance in that direction.
Example: A person with qualities of truth, austerity, patience, sense control, etc. would be encouraged to become a Brahman.
Such a person is fit to teach and impart education and knowledge to the other classes through conduct and also through teaching and preaching.
Once he accepts the role of a Brahman, he has to undergo the Ashrama system.
Brahmacharya Ashrama: First 25 years of his life. In this ashrama, he will stay under the care of a Guru or a Spiritual master. He would serve the spiritual master like a menial servant, gain knowledge, read and learn scriptures, observe strict celibacy, no meat-eating, no gambling, no intoxication etc.
Grahastha Ashrama: Next 25 years: Now, he would, if he wants, enter into married life. This allows regulated sense gratification. Like - sex should be only for the propagation of God conscious children. Not for sense-pleasure. He would continue his material life, while advancing in the spiritual discipline.
Vanaprastha Ashrama: Next 25 years of his life: Now he stays in family, but recedes from attachments to material possessions. Spends more time in developing his spiritual life and minimizes his material attachments, sense gratifications etc.
Sannyasa Ashrama: Next 25 years of his life: Now, the material life of the individual ends. He will severe his ties with his family. He will leave home. He will depend only on Supreme Lord for all his needs for sustenance. He would lead a completely spiritual life. This way experiencing the presence of a provider - God, in his life, depending on God, he will perfect his life and achieve the highest good - Spiritual Kingdom of God, after death.
Another point to note is that since we cannot find a trace of something does not mean it did not exist. The Vedas is not older than traces of human society. If there was human society then it had a system that made it a society. Just because Vedas mentions classes it does not make it the creator. You can state that Varna System taught classes how to be fair and just. But it appears that you state the Varna System created society. I am sure there was some other teaching before that created the first thing we could call society. Moreover if we look at the Vedas from my knowledge it is in a essentially lost language, it is very troublesome to study it. So how can we expect to go much further back then that, it becomes harder. Although there may be something traceable even far back that talks about the structure of society. I believe that Krishna was a Prophet of God who surely taught many things that brought us to be able to accept latter teachings. Definitely also had a big role in making us as capable society today.
You say that if we cannot find the trace of something, that does not mean it does not exist. Here the point of origin is being told clearly as Vedas - Vedic civilization. So, where is the need to speculate? However, a small difference is that you are taking the central purpose of the Vedas or religion as a means to improve society, social conditions etc. However, it is not the central point of religion. God Himself is the central point of Vedas or religion. Vedas have emanated FROM God. They are BY God. They are FOR God. For helping human civilization understand that their purpose is of going back to God, to the spiritual world...where we belong.
Unlike other religions, Vedas teach the Science of God. They tell us how the universe formed. How it will dissolve. What is heaven, what is hell, what are different punishments or rewards of both. They give us information of God, God's Kingdom, our relation with God....EVERYTHING!
Krishna is not a prophet. He is the Supreme Personality of Godhead. The scriptures declare it. The great prophets and seers have declared it. He Himself has declared it.
