These are some of the practical examples. There are persons who criticize the chanting of Hare Krsna mantra. Because the glories of the holy name are described here, sometimes those who are not in the line, they think, “It is too much. It is too much.” So it is advised, no it is not too much. You can test it. Test it. What is that test? When you fall down from a high place. Suppose from the roof you may fall down, you may slip and fall down. By falling down you may break your bones. Or you may be bitten by some animal — cats, dogs, a snake. There are so many, domestic. Or you may be burned or you may be injured by others. Then during this time you can test, practical. What is that test? Try to chant Hare Krsna. If anyone does so, you’ll immediately feel that from the injuries you are not feeling pain. This is practical. Even a snake bite you may be saved. The author never says that you may be saved from death, but the suggestion is that you may not feel much pain. This is practical.
