Kirtan is the fastest and sure shot way to evoke remembrance of the Lord.
Remembrance means remembrance of the Lord's name, form, qualities, pastimes, etc. Nitai is the treasurehouse where these glories of Gauranga Krishna are safely locked. Unless He opens up the treasure box, where is the hope of ever ascending to the terrace of premamayi smaranam bhakti? Nitainam is capable of opening that treasurehouse. Therefore we should wholeheartedly endeavor to distribute this magnanimous name to others, so that they may reap the greatest benefit of obtaining prema and Harinam Ruchi, while ourselves remaining immersed in the bliss of this 'nitya-anandamay' Nam. By hook or by crook, if they can somehow get Nitainam, they will surely get Krishna.
Just give Nitai to others (via Nitainam Lekhan), Nitai will give them the rest. Rest assured that they will surely attain all that is to be attained by Nitai's grace. To the extent that we have faith in this principle, to that extent we have realized the merciful nature of Nitaichandra.
If you are really desirous of a soul reaching Krishnachandra, be ambitious to give them Nitai's association. That's the real way they will attain Krishna without delay. Even if they have no idea who is Nitai, but somehow come in contact with Him through some pretext, Krishna Himself will go on a look out for that soul.
