Can Pind Daan be done online or through someone else if I can not go to Gaya?

In rare cases, due to health, age, or unavoidable circumstances, a proxy (sarva-sangrahi) may perform Pind Daan on your behalf. This should be arranged with a trustworthy Gaya Purohit, and you must send your consent and sankalp. While this is spiritually valid, personal presence is always superior, as the devotion and intention of the doer carry immense karmic weight.
