Bir Krishna Goswami - Lecture - Compassion and Empathy

From vedabase.net:

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 atmaupamyena refers to thinking others to be like oneself. One can very intelligently conclude that without devotional service, without becoming Krishna conscious, one cannot be happy. Therefore the duty of all devotees is to preach Krishna consciousness everywhere all over the world, because all living entities without Krishna consciousness are suffering the pangs of material existence. To preach Krishna consciousness is the best welfare activity. Indeed, it is described by Sri Caitanya Mahaprabhu as para-upakara, work for the true benefit of others. The activities of para-upakara have been especially entrusted to those who have taken birth in India as human beings.

bharata-bhumite haila manushya-janma yara
janma sarthaka kari' kara para-upakara(Cc. Adi 9.41)

The entire world is suffering for want of Krishna consciousness. Therefore Sri Caitanya Mahaprabhu advised all human beings born in India to make their lives perfect by Krishna consciousness and then preach the gospel of Krishna consciousness all over the world so that others may become happy by executing the principles of Krishna consciousness.
