Sarva-dharmān means there are so many system of religion. But any system of religion, if it does not lead you to the platform of devotional service to the Supreme Personality of Godhead, that is defective. Therefore Bhāgavata says, sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6). That is first class system of religion.
What is that? Which teaches one how to become unalloyed, unflinching devotee of the Supreme Personality of Godhead. That is first-class. All others, they are defective. Sometimes they are described as cheating. Like in the beginning of the Śrīmad-Bhāgavatam it is said dharmaḥ projjhita-kaitavo 'tra (SB 1.1.2). Kaitava means cheating. So anything going in the name of religion, but it is cheating, that is rejected here. Dharmaḥ projjhita. Projjhita means prakṛṣṭa-rūpeṇa ujjhita. Just like when you sweep with a broomstick, you cleanse all the dust, throw away, similarly, in the Śrīmad-Bhāgavatam, in the beginning it is said that cheating type of religious system is completely swept away. Dharmaḥ projjhita-kaitavo 'tra paramo nirmatsarāṇām (SB 1.1.2).
Then for whom it is meant for? Paramo nirmatsarāṇām. Those who have achieved the stage of nirmatsaratā, without any jealousy. Because the material disease is jealousy. I am jealous of you; you are jealous of me. This is the business here. Here however I may be very great personality, but in the material affairs—there are many instances—they become very very jealous. That is material disease. Material disease means we are all jealous. Therefore this bhāgavata-dharma, Kṛṣṇa consciousness movement, is meant for paramo nirmatsarāṇām, who is not jealous. For him it is meant for. Paramo nirmatsarāṇāṁ vāstavaṁ vastu vedyam atra. These are described there.
And actually our jealousy begins from Kṛṣṇa. Kṛṣṇa is asking, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66), but I am jealous, "Why shall I surrender to Kṛṣṇa? Why? Oh, He is also as good as I am; maybe little learned." Avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritam (BG 9.11). Because He is asking, demanding your surrender, and I am thinking He is an ordinary man, so I am losing the chance. Avajānanti māṁ mūḍhāḥ (BG 9.11). So our jealousy business has begun from Kṛṣṇa. "Oh, why shall I accept Kṛṣṇa as the Supreme Personality of Godhead?" Although in the śāstras Kṛṣṇa says personally mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya: (BG 7.7) "There is no more superior truth than Me," but we don't believe it. Although you read Bhagavad-gītā, but we don't accept Kṛṣṇa's version. This is our disease. Because jealousy. Jealousy. "Why shall I accept Kṛṣṇa as the Supreme?" This is jealousy. Therefore so long we are jealous, we cannot understand kṛṣṇa. Paramo nirmatsarāṇāṁ satām (SB 1.1.2). And who is not jealous? Satām. Satām. Those who are devotees.
- satāṁ prasaṅgān mama vīrya-saṁvido
- bhavanti hṛt-karṇa-rasāyanāḥ kathāḥ
- taj-joṣaṇād āśv apavarga-vartmani
- śraddhā ratir bhaktir anukramiṣyati
- (SB 3.25.25)
So we have to discuss about Kṛṣṇa amongst the Kṛṣṇa's devotees, not outsiders. Outsiders, they cannot understand Kṛṣṇa. They simply waste their time by commenting upon Bhagavad-gītā. Because they are mūḍhas, they cannot understand Kṛṣṇa. Kṛṣṇa said to Arjuna, "I shall explain Bhagavad-gītā because you are My bhakta." Bhakto 'si priyo 'si (BG 4.3). So who can understand Bhagavad-gītā unless he is a bhakta of Kṛṣṇa?
And therefore Kṛṣṇa selected Arjuna. Arjuna was not a Vedantist. He was a householder, kṣatriya, fighter, soldier. A soldier is not expected to be Vedantist, and neither very much well-versed in all the Vedic literature. That is not the business of kṣatriya. That is the business of a brāhmaṇa. Brāhmaṇa is paṇḍita. But kṣatriya is not supposed to become a paṇḍita. But still, Kṛṣṇa selected him. Kṛṣṇa, "Arjuna I shall speak to you the same old story which I spoke to..." Imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). "That is now lost. Therefore I shall revive it again, and I shall speak to you, because you are My bhakta, you are My friend."
