Very inspiring Praman from the 6th Chapter of "Shree Agastya-Samhita" (one of the Tantras from
"Shree PanchaRatra):
"Shree PanchaRatra):
Translation: "Those who die in front of Shree Tulasi never suffer in hells, because after leaving the bodies they reach ParamaPada (Shree Vishnu-Loka)".
And the similar Praman also from the 6th Chapter of "Shree Agastya-Samhita":
Translation: "Those punya-bhaktas, who die in vicinity of Shree Tulasi or Vishnu-Shalagrama-Shila, obtain Mukti - you should not have even a slightest doubt about this Mukti-Siddhanta!"
You can find a number of similar Pramans in "Shree Tulasi-Mahatmya" of "Shree Padma-Purana" as well!
