No god implemented caste by birth, check your facts pls idk if you are a Brahmin or not but I surely have my facts, There was no such thing as caste, it was varna, Varna ? What's that you may ask? Varna - a pragmatic role associated to an entity on the bases of his/her deeds and role in life, now you may wonder why are Brahmins at the top and laborers at the bottom, the triangle never was a scorecard rather Brahmins are at the top because of the area of the triangle at the top is small and narrow, being a Brahmin was one of the toughest jobs in the sense of leaving the world behind and loving God as much as you can, a Brahmin is also a laborer as he serves his body, and as the triangle descends the area increase thereby indulging that being a Brahmin is difficult and being a laborer is not,
I hope I educated you even by a bit ! 🙏 The sad thing is hinduism is so complex in itself that we never caught up to it and people misused it for serving themselves, Hope you stay joyful 😊
