Is online Pind Daan spiritually valid according to Hindu tradition?

Yes. The spiritual validity of Pind Daan rests on the authenticity of the ritual — the correct Vedic procedure, the correct mantras, the correct materials, performed at a genuine sacred tirtha by a qualified Pandit, in your name. Our online service meets every one of these requirements. The scriptures do not require the performer to be physically present at the site; they require the ritual to be genuine, which ours is.
