  Salutations to the gods. Desire performed the act. Desire did the act. Desire is doing the act, not I. O Desire, fascinating in form, let this oblations be offered to thee, Hail
  Salutations to the gods. Anger performed the act. Desire did the act. Anger is doing the act, not I. O anger, let this oblation be offered to thee.
These mantras as from Taittariya Aranyaka of Krishna Yajurveda.  The latter is found in rgveda also.  Brahmins belonging to the Krishna yajurveda school, chant a shortened form of this manthra every day once during  the oblations to  Sandhya three times a day.  On the upakarma day, this year it falls on today, this manthra  in shortened form is repeated 1008 times as expiation by way of confession that many of our acts are instigated by desire and anger over which we have little control most of the time, and, therefore we are trying to propitiate them so that they will get out of our way.
