It is said in BG 7.17 priyo hi jñānino 'tyartham aham ca mama priyaḥ. The Lord says that those who are advanced in transcendental knowledge and know the science of Kṛṣṇa consciousness are very dear to Him, and He also is very dear to them. Those who are actually in perfect knowledge of the science of God know that the living entities are superior energy of the Supreme Lord. This is stated in Bhagavad-gītā, Seventh Chapter: the material energy is inferior, and the living entities are superior energy. Energy and the energetic are nondifferent; therefore, energies possess the same quality as the energetic. Persons who are in full knowledge of the Personality of Godhead, analyzing His different energies and knowing their own constitutional position, are certainly very, very dear to the Lord. Persons, however, who may not even be conversant with knowledge of the Supreme Personality but who always think of the Lord with love and faith, feeling that He is great and that they are His parts and parcels, ever His servitors, are even more favored by Him.
The particular significance of this verse is that the Lord is addressed as vatsala. Vatsala means "always favorably disposed." The Lord's name is bhakta-vatsala. The Lord is famous as bhakta-vatsala, which means that He is always favorably inclined to the devotees, whereas He is never addressed anywhere in the Vedic literature as jñānī-vatsala.
