Angushtha-tarjanee yogamudra vyaajaena dachinaam Shrutyartham
brahmajeevaikyam darshartham brahmajeevaikyam Darshayanno(a)
The lord dakishnamurthy holds his thumb and index finger (tarjanee)
And exhibits yoga mudra, which convey his form that he is a perfect yogi
When one hears him, it appears as though he is merged with Brahman.
When he Is seen he appears to be the very manifestation of lord shiva.
