Sridhara Swami in his commentary has said, that pious activities (dharma), economic development (artha), satisfaction of the senses (kama), and finally liberation from material bondage (moksa) are all external factors. And the real dharma or religious principle is devotional service to the Lord. This is real.

So the mission of Caitanya Mahaprabhu is that it is appropriate for all Indians to travel all over and preach this message of Lord Sri Krishna. So this is the mission of Krishna consciousness movement. This is not an ordinary religious movement, it is religious but nowadays religions are many. Real religious principles (dharma) is one, dharmaṁ tu sākṣād bhagavat-praṇītaṁ (SB 6.3.19), dharma or real religious principles cannot be enacted by anyone. These can be enacted only the Supreme Lord. So the dharma that the Lord is propagating is sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66), that “all of you surrender unto Me.” This is the only real religion. The rest are all cheating religion. That is why in the beginning of Srimad Bhagavatam it is said, dharmaḥ projjhita-kaitavo ’tra (SB 1.1.2) all these cheating types of religions has been thrown out from this scripture, projjhita, prakrsta-rupena ujjhita.
In this regard Sridhara Swami in his commentary has said, that pious activities (dharma), economic development (artha), satisfaction of the senses (kama), and finally liberation from material bondage (moksa) are all external factors. And the real dharma or religious principle is devotional service to the Lord. This is real, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66).
So the teachings of Caitanya Mahaprabhu is that all of you become guru and to become guru is not a difficult thing. If your intention is not to cheat, then it is not a difficult thing. Because what is the work of a guru? Whatever Lord Sri Krishna has spoken in the Bhagavad Gita, you speak the same. What is the difficulty in this? The Lord says in the Bhagavad Gita, mattaḥ parataraṁ nānyat kiñcid asti dhanañ-jaya (BG 7.7) that - there is no truth superior to Me. These are all scriptural evidences :
īśvaraḥ paramaḥ kṛṣṇaḥ
sac-cid-ānanda-vigrahaḥ
anādir ādir govindaḥ
sarva-kāraṇa-kāraṇam
(BS 5.1)
and
kṛṣṇas tu bhagavān svayaṁ
and then the Lord Himself says, when Arjuna understood the Bhagavad Gita, he said, paraṁ brahma paraṁ dhāmapavitraṁ paramaṁ bhavān (BG 10.12). So Lord Sri Krishna is the Absolute Truth, this is the scriptural conclusion, all the acaryas have accepted this. Sankaracarya has also accepted this sa bhagavan svayam krsna. And Ramanujacarya, Madhvacarya, Nimbarka, Visnuswami, and what to speak of Caitanya Mahaprabhu, kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ (SB 11.5.32) He was always speaking about Krishna, the essence of all Vedic scriptures, vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). What is the purpose of reading the Vedic scriptures – to understand Supreme Lord Krishna. This is the conclusion of all Vedic scriptures.
