BG Chap 9 - The impartial Lord who is partial
Is Kṛṣṇa partial in liberating the devotees but not the non-devotees? Kṛṣṇa is equal to all living beings. He neither hates nor favors anyone. As one surrenders, Kṛṣṇa reciprocates. All living beings are under the control of their karmas. The Lord is equal to all like the rain, which sprinkles water on all varieties of seeds. But those who worship Him with devotion are in Him, and He is also in them. There is nothing special about this since the whole universe exists within the Lord, and the Lord exists everywhere in the universe. Thus what Kṛṣṇa means is to whatever extent a person worships Him with devotion, He is attached to that person in a similar way. Those who please Him with hearing and other forms of bhakti exist in Him because of attraction to Him. He exists in them because of attraction to them.
The Lord’s love for the devotees is like the combination of jewels and gold, which mutually enhance each other, creating more beauty than either of the objects alone. Comparing Kṛṣṇa to a desire tree is only partially apt, for in the desire tree one does not see mutual affection and partiality. Though equal to all, the Lord does show partiality by having affection for those who take shelter of Him. Bhakti arises from the svarūpa śakti of the Lord, and so the affection the Lord has for His devotees is outstanding. This affection also arises from the Lord’s svarūpa, but this is not a fault but an ornament in the Lord. The affection for the devotee is an accomplished fact. The Lord does not have affection for the jñānī or the yogī, nor for the devotees of Śiva or Durgā.
