Śrīmad-Bhāgavatam
[Canto 7, Ch. 7]
TRANSLATION
My dear friends, O sons of the demons, in the same favorable way that one sees himself and takes care of himself, take to devotional service to satisfy the Supreme Personality of Godhead, who is present everywhere as the Supersoul of all living entities.
PURPORT
The word  ātmaupamyena  refers to thinking others to be like oneself. One can very intelligently conclude that without devotional service, without becoming Krṣṇa conscious, one cannot be happy. Therefore the duty of all devotees is to preach Krṣṇa consciousness everywhere all over the world, because all living entities without Krṣṇa consciousness are suffering the pangs of material existence. To preach Krṣṇa consciousness is the best welfare activity. Indeed, it is described by Śri Caitanya Mahāprabhu as  para-upakāra , work for the true benefit of others. The activities of  para-upakāra  have been especially entrusted to those who have taken birth in India as human beings.
bhārata-bhūmite haila manuṣya-janma yāra janma sārthaka kari' kara para-upakāra  (Cc.  Ādi  9.41)
The entire world is suffering for want of Krṣṇa consciousness. Therefore Śri Caitanya Mahāprabhu advised all human beings born in India to make their lives perfect by Krṣṇa consciousness and then preach the gospel of Krṣṇa consciousness all over the world so that others may become happy by executing the principles of Krṣṇa consciousness.
