Prachar is not for Prachar's sake, it is not for mundane temporary benefits. Wherever we may go or stay by the will of Supreme Lord Sree Krishna, Who is All-Good, we should perform Bhajan (devotional practice), we should not forget the devotional purpose of our life. Everything will remain in this world, nothing will go with us. So, it will be unwise to sacrifice eternal benefit for the sake of mundane temporary benefits.
It will be wise to perform all forms of Bhajan including Kirtan for the propitiation of Sree Krishna and His devotees. Chanting of the glories of Sree Krishna— His Name, Form, Attributes and Pastimes is the best form of Bhakti. While performing Bhakti (Kirtan Bhakti), prachar will be automatic. There is no need of making separate endeavour for this.
