This is the divinity of the Personality of Godhead: He is not affected by the qualities of material nature, even though he is in contact with them. Similarly, the devotees who have taken shelter of the Lord do not become influenced by the material qualities.
If you want to develop a particular quality, then serve the devotee who has that quality.
When the Vedic literature describes the Personality of Godhead as being without any qualities (nirguna), this means that the Lord does not possess any material qualities. It does not mean that He has no spiritual qualities.
When we stand before the Lord, we should be meditating on how we can develop the qualities and the characteristics by which he will really be pleased to see us. Then, when we have such a consciousness, he actually reveals himself to us.
