Only Dharma
There is actually one dharma, love of Godhead. Dharma means you love God & automatically you will love all living entities, because they are also children of Krishna.
Desires
“na te vidu svartha-gati hi Vishnum” – Who don’t know the ultimate goal of life is to please Krishna, Narayana, Hari. ‘Durashaya‘ – they have got unlimited desires to fulfill that is all durashaya, he will never satisfy himself. But the devotee is always happy & satisfied because he always desires to please Krishna.
Hankering
A vaishnava is never after any hankerings, he does not hanker for name, fame, beauty, wealth etc. A karmi always hankers for all these things and forgets Krishna.
Training
We can shape a green bamboo as we desire, but old bamboo cannot be changed. As hard as we try, it will break. So it is better to be trained as a devotee while young.
