For the past ten years, I have been compiling the Avani avitta manthras(Upakarma manthras ) every year and putting in the web so that it is available to those who are not able to get them or to those who know only English. I know many other people are doing this job.Last year I came across a reference where even the audio is given. I am still doing it in the hope that at least one person in this wide world would find it useful.
This year the Yajur Vedi and Rig Vedi Avani Avittam falls on 13-8-2011, Gayathri Japam for all Vedas on 14-8-2011 and the Sama Vedi Avani avittam falls on 31-8-2011 according to the Madathu Panjangam which I follow.
The Yajur Vedi and Rig Vedi mantras are given in
and the Sama Vedi Upakarma mantras are given in
Hope you may find them useful, Ramachander
