The resolute purpose of a person in Kṛṣṇa consciousness is based on knowledge. Vāsudevaḥ sarvam iti sa mahātmā su-durlabhaḥ: a person in Kṛṣṇa consciousness is the rare good soul who knows perfectly that Vāsudeva, or Kṛṣṇa, is the root of all manifested causes. As by watering the root of a tree one automatically distributes water to the leaves and branches, so by acting in Kṛṣṇa consciousness one can render the highest service to everyone—namely self, family, society, country, humanity, etc. If Kṛṣṇa is satisfied by one's actions, then everyone will be satisfied.
(Bhagavad-Gita----2:41----purport).
Only the brāhmaṇas and sannyāsīs are authorized to accept charity from the householders. In all the different occasions of saṁskāras, especially during the time of birth, marriage and death, wealth is distributed to the brāhmaṇas because the brāhmaṇas give the highest quality of service in regard to the prime necessity of humankind. The charity was substantial in the shape of gold, land, villages, horses, elephants and food grains, with other materials for cooking complete foodstuff. The brāhmaṇas were not, therefore, poor in the actual sense of the term. On the contrary, because they possessed gold, land, villages, horses, elephants and sufficient grains, they had nothing to earn for themselves. They would simply devote themselves to the well-being of the entire society.
(Srimad Bhagavatam----1:12:14----purport).
Lord Caitanya exhibited the mode of Śrīmatī Rādhārāṇī when She was contacted from Dvārakā by Śrī Kṛṣṇa. Such transcendental love is not possible for any common man; therefore one should not imitate the highest perfectional stage exhibited by Caitanya Mahāprabhu. If, however, one desires to be in that association, he may follow in the footsteps of the gopīs. In the Padma Purāṇa it is stated that just as Rādhārāṇī is dear to Kṛṣṇa, similarly the kuṇḍa known as Rādhākuṇḍa is also very dear to Him. Rādhārāṇī is the only gopī who is dearer to Kṛṣṇa than all the other gopīs. In Śrīmad-Bhāgavatam (10.30.28) it is also stated that Rādhārāṇī and the gopīs render the highest perfectional loving service to the Lord and that the Lord is so pleased with them that He does not wish to leave the company of Śrīmatī Rādhārāṇī.

The highest position in the world is to be servant of Krishna. It means to have no other motivation except to serve Krishna. Service does not mean I do what I want, when I want. Service means whatever makes Krishna happy.
