In this material world, the so-called dharmas, Hindu dharma, Muslim dharma and Christian dharma and Buddhist dharma and so many… They are not sad-dharma (eternal dharma). They are asad-dharma (temporary religions). “Because I am born in the family of a Christian, I am Christian.” “Because I am born in the family of Hindu, I am Hindu.” And next time I may (be) born in the family of a dog, then there is no dharma. So these are not sad-dharma. These are all asad-dharma, for the time being.
Asad means “that, which will not stay.” You are Hindu. How long you are Hindu? Say, fifty years. Or you are Indian. How long you are Indian? Say, fifty, sixty, hundred years. But again you have to become something else. That we do not know. We are working very hard, “I am Hindu,” “I am Muslim,” “I am Indian,” “I am American.” These are upādhi (designations). But the upādhi, or designation may be changed at the next moment. This is temporary dharma for the body.
So what is your real dharma? Real dharma is sarva-dharmān parityajya mām ekam śaranam vraja [Bg. 18.66]: “Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear.” That is sad-dharma. That will continue eternally.
Here it is said, namāmi sad-dharma-vidām varistham (SB 3.25.11): “There are many propounders of sad-dharma. But actually, You are the best of the propounders of the sad-dharma because You know the reality.” And that is the actual reality: sarva-dharmān parityajya mām ekam śaranam vraja [Bg. 18.66]: Abandon all varieties of religion and just surrender unto Me. That is sad-dharma.
So the Gosvamis worked (to establish sad dharma). Sad-dharma samsthāpakau. These Gosvamis, who were Sri Chaitanya Mahaprabhu’s direct disciples, tried to establish sad-dharma, and we are trying to follow their footprints, footsteps, in order to establish real dharma all over the world. This is the Krishna consciousness movement.
