1. Great acaryas introduce study of the Vedas

    After the first rainfall, when there is a thundering sound in the clouds, all the frogs begin to croak, like students suddenly engaged in reading their studies. Students are generally supposed to rise early in the morning. They do not usually arise of their own accord, however, but only when there is a bell sounded in the temple or other spiritual institution. By the order of the spiritual master they immediately rise, and after finishing their morning duties they sit down to study the Vedas or chant Vedic mantras. Everyone is sleeping in the darkness of Kali-yuga, but when there is a great acarya, by his calling only, everyone takes to the study of the Vedas to acquire actual knowledge.
