The extraordinary power of the Lord's holy name

[Bhakti Vikasa Swami]

Ajamila's exalted position as a brahmana was vanquished by his association with
the prostitute, so much so that he forgot all his brahminical activities.
Nevertheless, at the end of his life, by chanting the four syllables of the
name Narayana, he was saved from the gravest danger of falling down. Svalpam
apy asya dharmasya trayate mahato bhayat: even a little devotional service can
save one from the greatest danger. Devotional service, which begins with
chanting of the holy name of the Lord, is so powerful that even if one falls
down from the exalted position of a brahmana through sexual indulgence, he can
be saved from all calamities if he somehow or other chants the holy name of the
Lord. This is the extraordinary power of the Lord's holy name. Therefore in the
Bhagavad-gita it is advised that one not forget the chanting of the holy name
even for a moment (satatam kirtayanto mam yatantas ca drdha-vratah [Bg. 9.14]).
There are so many dangers in this material world that one may fall down from an
exalted position at any time. Yet if one keeps himself always pure and steady
by chanting the Hare Krsna maha-mantra, he will be safe without a doubt.
