Lord Śrī Kṛṣṇa instructed Uddhava that by following the injunctions of the social and spiritual orders of human society, one can satisfy the Supreme Personality of Godhead, and as a result of such satisfaction the whole society gets all the necessities of life amply and without difficulty. This is because, after all, the Supreme Personality of Godhead maintains all other living entities. If the whole society performs its respective duties and remains in Kṛṣṇa consciousness, there is no doubt that all of its members will live very peacefully and happily. Without wanting the necessities of life, the whole world will be turned into Vaikuṇṭha, a spiritual abode. Even without being transferred to the kingdom of God, by following the injunctions of Śrīmad-Bhāgavatam and prosecuting the duties of Kṛṣṇa consciousness all human society will be happy in all respects.
There is a similar statement by Śrī Kṛṣṇa Himself to Uddhava, in the Eleventh Canto of Śrīmad-Bhāgavatam, Twenty-seventh Chapter, verse 49. The Lord says there, "My dear Uddhava, all persons are engaged in activities, whether those indicated in the revealed scriptures or ordinary worldly activities. If by the result of either of such activities they worship Me in Kṛṣṇa consciousness, then automatically they become very happy within this world, as well as in the next. Of this there is no doubt." We can conclude from this statement by Kṛṣṇa that activities in Kṛṣṇa consciousness will give everyone all perfection in all desires.
Thus the Kṛṣṇa consciousness movement is so nice that there is no need of even designating oneself brāhmaṇa, kṣatriya, vaiśya, śūdra, brahmacārī, gṛhastha, vānaprastha or sannyāsī. Let everyone be engaged in whatever occupation he now has. Simply let him worship Lord Kṛṣṇa by the result of his activities in Kṛṣṇa consciousness. That will adjust the whole situation, and everyone will be happy and peaceful within this world. In the Nārada Pañcarātra the regulative principles of devotional service are described as follows: "Any activities sanctioned in the revealed scriptures and aiming at the satisfaction of the Supreme Personality of Godhead are accepted by saintly teachers as the regulative principles of devotional service. If one regularly executes such service unto the Supreme Personality of Godhead under the direction of a bona fide spiritual master, then gradually he rises to the platform of serving in pure love of God."
