That is stated here: sva-bhṛtya-saṁsāra-taroḥ kuṭhāram, jijñāsayāhaṁ prakṛteḥ pūruṣasya namāmi sad-dharma-vidāṁ variṣṭham. Sad-dharma. Not sad-dharma. Asato mā sad gama. So sad-dharma required. The, in this material world the so-called dharmas, this Hindu dharma, Muslim dharma and Christian dharma and Buddhist dharma and so many... They are not sad-dharma. They are asad-dharma. "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. There is no dharma. So these are not sad-dharma. These are all asad-dharma, for the time being. Asad means "that 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 upādhi. But the upādhi may be changed next moment. At any moment. So what is your real dharma? This is temporary dharma for the body. What is your real dharma? Real dharma is sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). That is sad-dharma. That is sad-dharma. That will continue eternally.
So sad-dharma... Here it is said, namāmi sad-dharma-vidāṁ variṣṭham: "There are many propounder 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 ekaṁ śaraṇam... (BG 18.66). That is sad-dharma. So the Gosvāmīs worked... Sad-dharma-saṁsthāpakau. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau. So these Gosvāmīs, Śrī Caitanya Mahāprabhu's direct disciples, they tried to establish sad-dharma, and we are trying to follow their footprints, footsteps, to establish real dharma all over the world. This is Kṛṣṇa consciousness movement.
