Srimad Bhagavatam Canto 09, Chapter 16, Text 23

SB 9.16.23

tatas cavabhrtha-snana-
sarasvatyam maha-nadyam
 reje vyabbhra ivamsuman
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Thereafter, having completed the ritualistic sacrificial ceremonies, Lord Parasurama took the bath known as the avabhrtha-snana. Standing on the bank of the great river Sarasvati, cleared of all sins, Lord Parasurama appeared like the sun in a clear, cloudless sky.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
As stated in Bhagavad-gita (3.9), yajñarthat karmano ’nyatra loko ’yam karma-bandhanah: “Work done as a sacrifice for Visnu has to be performed; otherwise work binds one to this material world.” Karma-bandhanah refers to the repeated acceptance of one material body after another. The whole problem of life is this repetition of birth and death. Therefore one is advised to work to perform yajña meant for satisfying Lord Visnu. Although Lord Parasurama was an incarnation of the Supreme Personality of Godhead, he had to account for sinful activities. Anyone in this material world, however careful he may be, must commit some sinful activities, even though he does not want to. For example, one may trample many small ants and other insects while walking on the street and kill many living beings unknowingly. Therefore the Vedic principle of pañca-yajña, five kinds of recommended sacrifice, is compulsory. In this Age of Kali, however, there is a great concession given to people in general. Yajñaih sankirtana-prayair yajanti hi sumedhasah: we may worship Lord Caitanya, the hidden incarnation of Krsna. Krsna-varnam tvisakrsnam: although He is Krsna Himself, He always chants Hare Krsna and preaches Krsna consciousness. One is recommended to worship this incarnation by chanting, the sankirtana-yajña. The performance of sankirtana-yajña is a special concession for human society to save people from being affected by known or unknown sinful activities. We are surrounded by unlimited sins, and therefore it is compulsory that one take to Krsna consciousness and chant the Hare Krsna maha-mantra.
