The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be unmotivated and uninterrupted in order to completely satisfy the self."
If the members of human society actually want peace of mind, tranquillity and friendly relations between men and nations, they must follow the Kṛṣṇa conscious system of religion, by which they can develop their dormant love for Kṛṣṇa, the Supreme Personality of Godhead. As soon as people do so, their minds will immediately be filled with peace and tranquillity.
In this regard, Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura warns all devotees engaged in broadcasting the Kṛṣṇa consciousness movement not to speak to the impersonalist Māyāvādīs who are always determined to oppose such theistic movements. The world is full of Māyāvādīs and atheists, and the political parties of the world take advantage of Māyāvāda and other atheistic philosophies to promote materialism. Sometimes they even back a strong party to oppose the Kṛṣṇa consciousness movement. The Māyāvādīs and other atheists do not want the Kṛṣṇa consciousness movement to develop because it educates people in God consciousness. Such is the policy of the atheists. There is no benefit in feeding a snake milk and bananas because the snake will never be satisfied. On the contrary, by taking milk and bananas the snake simply becomes more poisonous (kevalaṁ viṣa-vardhanam). If a snake is given milk to drink, its poison simply increases. For a similar reason, we should not disclose our minds to the serpent Māyāvādīs and karmīs. Such disclosures will never help. It is best to avoid association with them completely and never ask them about anything confidential because they cannot give good advice. Nor should we extend invitations to Māyāvādīs and atheists nor accept their invitations, for by such intimate intermingling we may become affected by their atheistic mentality (saṅgāt sañjāyate kāmaḥ). It is the negative injunction of this verse that we should refrain from giving anything to or accepting anything from the Māyāvādīs and atheists. Śrī Caitanya Mahāprabhu has also warned, viṣayīra anna khāile duṣṭa haya mana: (CC Antya 6.278) "By eating food prepared by worldly people, one s mind becomes wicked. Unless one is very advanced, he is unable to utilize everyone's contribution to further the Kṛṣṇa consciousness movement; therefore on principle one should not accept charity from the Māyāvādīs or atheists. Indeed, Śrī Caitanya Mahāprabhu has forbidden devotees to associate even with ordinary men who are too addicted to material sense gratification.
The conclusion is that we should always keep company with devotees, observe the regulative devotional principles, follow in the footsteps of the ācāryas and in full obedience carry out the orders of the spiritual master. In this way we shall be able to develop our devotional service and dormant Kṛṣṇa consciousness. The devotee who is neither a neophyte nor a mahā-bhāgavata (a greatly advanced devotee) but is within the middle status of devotional service is expected to love the Supreme Personality of Godhead, make friends with the devotees, show favor to the ignorant and reject the jealous and demoniac. In this verse there is brief mention of the process of making loving transactions with the Supreme Personality of Godhead and making friends with the devotees. According to the dadāti principle, an advanced devotee is supposed to spend at least fifty percent of his income on the service of the Lord and His devotees. Śrīla Rūpa Gosvāmī has set such an example in his life. When he decided to retire, he distributed fifty percent of his life's earnings to Kṛṣṇa's service and twenty-five percent to his relatives and kept twenty-five percent for personal emergencies. This example should be followed by all devotees. Whatever one's income, fifty percent should be spent on behalf of Kṛṣṇa and His devotees, and this will fulfill the demands of dadāti.
In the next verse, Śrīla Rūpa Gosvāmī informs us what kind of Vaiṣṇava should be selected as a friend and how Vaiṣṇavas should be served.
