Having experienced that in external consciousness there is no happiness and Krishna consciousness only gives true happiness, the yogi tries to help everyone, without distinction between friend and enemy, to become happy by turning their consciousness to Krishna
aA Krishna conscious person is a perfect yogi — Because aware of real cause of happiness and distress by dint of his personal experience
The cause of distress – Forgetfulness of relationship with God
The cause of happiness – Knowing Krishna to be the Supreme enjoyer, the Supreme proprietor and the sincerest friend
bA Krishna conscious person is the best philanthropist and dearest servitor of the Lord – Because he tries to broadcast the importance of Krishna consciousness
Ref. Bg. 18.69 “na ca tasman...”
He is the best yogi because he does not desire perfection in yoga for his personal benefit but tries for others also
This differentiates a pure devotee from a yogi only interested in personal salvation
