It is said here that amongst the trees there are also evolutionary processes; the different kinds of trees have touch perception. It is said that better than the trees are the fish because fish have developed the sense of taste. Better than the fish are the bees, who have developed the sense of smell, and better than them are the serpents because serpents have developed the sense of hearing. In the darkness of night a snake can find its eatables simply by hearing the frogs very pleasant cry. The snake can understand, There is the frog, and he captures the frog simply because of its sound vibration. This example is sometimes given for persons who vibrate sounds simply for death. One may have a very nice tongue that can vibrate sound like the frogs, but that kind of vibration is simply calling death. The best use of the tongue and of sound vibration is to chant Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. That will protect one from the hands of cruel death.
