Your late husband would not have been subject to such a suffering because he was a follower of Nichiren, a practicer of the Lotus Sutra. The Lotus Sūtra states: “Those who call upon the name of the Buddha will not be burned even if they fall into a great fire; they will immediately run ashore if carried away by a flood.” It states also: “Fire cannot burn the merit of practicing the teaching of the Lotus Sutra, and water cannot wash it away.” How reliable it is!
