Only six months were spent in Veda learning, meaning the time taken to complete the study was way too long, so utsarjana was slowly skipped #Upakarma
आयुष्यमग्रयं प्रतिमुंञ्च शुभ्रं। यज्ञोपवितम् बलमस्तुतेज:।।
"This Yagyopaveeta, most sacred, through Prajapati in the beginning, giving Long Life, worn as White Thread, Strengthens & gives splendour"
That is the student's way of recognition that we are what we are, because of who our forefathers and founding Rishis were! #upakarma
