Whosoever desires to worship whatever deity with faith, I make their faith steady in that very deity.
When your intellect, that is confused by the conflicting opinions and the ritualistic doctrine of the Vedas, shall stay steady and firm with the Self, then you shall attain Self-realization.
Endowed with steady faith they worship that deity, and fulfill their wishes through that deity. Those wishes are, indeed, granted only by Me.
Arjuna said: O Krishna, You have said that yoga of meditation is characterized by the equanimity (of mind), but, due to restlessness of mind I do not perceive the steady state of mind.
Because the calm person, who is not afflicted by these feelings and is steady in pain and pleasure, becomes fit for immortality, O Arjuna.
