Jai Sri Ganesha,
Yajna is an aspect of sacrifice that is meant to sanctify the heart and mind at its requisite pitch,
Yajna is not that reciting and offering material in the sacred fire, it is a pious vow and pledge that makes this offering and recital to the truth of Yajna that snactify the self,
Yajna must be regarded as a great sacrifice but it needs offering with capacity of individual, does not need any show business beyond the capacity of individual concerned,
Yajna is a live boon to human to participate and yield best eternally to charm self with inherent joy,
Jai Mahadev
