[Advaita-l] Sandhyavandana procedure doubt

[Venkata sriram P]

Namaste,
 
vikacchOnuttarIyascha nagnascha avastrascha; shrauta smArtE naiva kuryAt
 
Without uttarIyaM, the dvija is considered to be digaMbara (nagnascha & avastrascha).
Such a person is not eligible for shrauta & smArta karmAs.
 
However, if accidentally, one forgets to have uttarIyaM, the *truteeya yajnOpaveeta* saves
the modesty.  Hence, during yajnOpaveeta dhAraNa, the sankalpa made is
 
*uttareeyArthaM truteeya yajnOpaveeta dhAraNaM kariSyE*.
 
The prathama yajnOpavita is for brahmachAri as a part of upanayana samskAra 
to get the adhikAra for agni kArya.  The dviteeya yajnOpavita is during *samAvartana*
ie, snAtaka mahOtsava.  The truteeya yajnOpavita is for uttareeya.
 
So, one should don the uttareeya always without which one is unfit for shrauta & smArta karmAs.  
 
regs,
sriram
