1. In our scriptures, Jaati is by birth. Varna is by action. There is not supposed to be any Jaati or Verna differences.
2. Every Jaati, every varna has their forte, and each one was proud of what they were and each one was contributing members of the society.
3. All possible combinations of Jaati and Verna were present. As children grew up, they picked the path of their liking.. that is what the previous Hindi post was saying with examples over millenniums.
4. Scriptures do not say Verna are a strict pyramid with brahmins on top. It was depiction by people of Abrahamic faiths when they looked at the Scriptures from their background.
5. Our scriptures depict Hindu society as a circle of Verna and a circle of Jaati. Each Jaati and Verna being part of the circle – a pie chart making a full circle. Clearly telling that Hindu society is not complete if any of them is missing. And each member of any Jaati or Verna would progress through four ashrams during their life thus each one attaining heavenly abode (or nirvana or self realization or eternal life with the God as they desire).
6. Society and customs had well defined interrelationship such that everyone will need everyone else many times during their life
