Very well said by Sri Sarma Sastrigal. I would add to this and say that this is Brahmin’s #1 responsibility. It is our responsibility as there is a puranic background for this karma. Sri Dikshitar told this to us long back – I vaguely remember. Let met try – when we do “”Asavadithyo Brahma, Brahmaiva Satyam, Brahmaiva Aham asmi” – we sprinkle water twice over our head. It seems that by doing this we drive Rahul/ketu away from hiding Sun. That is our responsibility. I could be wrong. Anyways – do the sandhyavandhanam thrice a day and let us try to elevate ourselves in the spiritual journey.
