Krishna's Mercy on Narada

SB 1.6.22: O virtuous one, you have only once seen My person, and this is just to increase your desire for Me, because the more you hanker for Me, the more you will be freed from all material desires.

PURPORT

A living being cannot be vacant of desires. He is not a dead stone. He must be working, thinking, feeling and willing. But when he thinks, feels and wills materially, he becomes entangled, and conversely when he thinks, feels and wills for the service of the Lord, he becomes gradually freed from all entanglement. The more a person is engaged in the transcendental loving service of the Lord, the more he acquires a hankering for it. That is the transcendental nature of godly service. Material service has satiation, whereas spiritual service of the Lord has neither satiation nor end. One can go on increasing his hankerings for the loving transcendental service of the Lord, and yet he will not find satiation or end. By intense service of the Lord, one can experience the presence of the Lord transcendentally. Therefore seeing the Lord means being engaged in His service because His service and His person are identical. The sincere devotee should go on with sincere service of the Lord. The Lord will give proper direction as to how and where it has to be done. There was no material desire in Nārada, and yet just to increase his intense desire for the Lord, he was so advised.
