The basic dharma is live and let live without as far as possible knowingly hurt any one. If you are always selfish, when you have COVID you will die alone, Refuse to give bribe because poor people don't have the luxury. While we may look and behave as strangers, we have evolved from the same stock that lived thousands of years back. So, if don't help don't hurt. Share if you can, but don't stop some one who wants to help. -- I live by this and almost always happy and my friends and relatives cherish my relationship with them. I eat in Muslim House, Harijan's house but stipulate that I have allergy for non-veg, don't like too much garlic, I don't eat much and I want a cupy of yogurt(Dhahi) and they oblige. So, for me the only rational is the other person good or not. If not good I move away. While this is my philosophy of life, I don't expect others to follow, because I move away from those who are selfish and discrimnatory.Let's discuss this not as a conundrum to Brahmins alone but to anyone who wants to lead a dharmic life.
What is a dharmic life? I believe the simplest approach is live in accordance with what our conscience tells us. Conscience is both a timeless aspect of mind in essence but conditioned by realities of one's current birth, which are approved and acceptable.
So it is my belief that there is an external àspect also to one's conscience. If we go by the way of conscience I think the dharmic requirements will be satisfied.
The next question is, how practical and applicable is this solution in current times? I think it is a workable one if we approach it in the right way. Inner wise I think the aspect antagonistic to conscience is our ego. So I think if we are able to rein in our ego which is by no means an easy task, we can let our conscience function properly and powerfully and act in accordance with it.
Ego is something like a veil over our conscience. It is a stupendous task to totally lift it but even if we make sincere efforts in that direction very fruitful results can be achieved. The will to achieve is as important as the process of achieving.
