1. Chanting: the best sacrifice

    Of all the sacrifices mentioned in the Vedic literatures, the performance of sankirtana-yajna is the best. Even the performance of one hundred asvamedha sacrifices cannot compare to the sacrifice of sankirtana. According to the author of Sri Caitanya-caritamrta, if one compares sankirtana yajna to other yajnas, he is a pasandi, an infidel, and is liable to be punished by Yamaraja.
  2. By chanting, become a full moon

    If you understand your position, then what is your real occupation, real activities, you will understand. Ceto-darpana-marjanam bhava-maha-davagni-nirvapanam sreyah-kairava-candrika-vitaranam [Cc. Antya 20.12]. Just like the moon rises from a line. On the Pratipat day, on the first moon side, you will see just like a line, but gradually it develops, develops, develops, and it becomes a full moon, very beautiful.
