what are the three important things which should be applied or carried on our body if not so the good deeds won't be able to earn us virtues?
A) the three things are first yagnopaveetam ( for women mangala sutramu), second one is shikha bandhanam (tuft or lock of hair on head, common for women and men), third one is urdhwa pundra naama dhaaranam of gopichandanam, without these what ever good karma or deeds we do will result in waste or no use.
उपवीतं शिखाबन्धं ऊर्ध्वपुन्ड्रं विना कृतम् ।
अपवित्र कृतं कर्म विप्रस्य विफलं भवेत् ।।
