Hari-tosanam… samsiddhim hari-tosanam, that you get all perfection when you satisfy Krishna. Sacrifice is not something abstract but it means to, satisfy the Lord. So what can be more satisfying to the Lord in this Kali- yuga than chanting His holy names? Because by this all the people are benefited.
“Thus by their cooperation of all classes of human beings, the sacrifice recommended in this age, namely the sacrifice of congregational chanting of the holy name of the Lord, may be executed for the common welfare of all the people of the world.” (SB 2.1.37 Purport)
