There are innumerable names of the Lord both in India and outside, and all of them are equally good because all of them indicate the Supreme Personality of Godhead. But because these sixteen are especially recommended for this age, people should take advantage of them and follow the path of the great ācāryas who attained success by practicing the rules of the śāstras (revealed scriptures).
The simultaneous occurrence of the Lord's appearance and the lunar eclipse indicated the distinctive mission of the Lord. This mission was to preach the importance of chanting the holy names of the Lord in this age of Kali (quarrel). In this present age quarrels take place even over trifles, and therefore the śāstras have recommended for this age a common platform for realization, namely chanting the holy names of the Lord. People can hold meetings to glorify the Lord in their respective languages and with melodious songs, and if such performances are executed in an offenseless manner, it is certain that the participants will gradually attain spiritual perfection without having to undergo more rigorous methods.
