True Love

Moses, a great devotee and lover of God, requested God to bring him in contact with or point out to him a greater and a better lover of God than himself and God pointed to a bird upon a tree not far away.

When Moses approached the bird and asked if there was anything that it wanted or that he could do for it, the bird replied that it was perfectly satisfied and happy except for one thing. Moses asked what that was. The bird said that it wished it did not have to leave its perch to go for water. Moses was astonished at this and pointed out that the bird was perched on a tree immediately above the water and all it had to do was to fly down a few feet to take a drink. The bird replied, “That is true, but I am always thinking of God, and the time spent in flying down and taking a drink takes me away from the contemplation of my love for God for a few minutes. That is my only regret.”

Upon hearing this, Moses felt ashamed and realized that this bird loved God more than he did.
_{Maharaj Sawan Singh, Spiritual Gems}

During simran the longing for God in one’s mind
  Should be as intense as that of a lover for the beloved,
  While sitting, standing, awake or asleep,
The form of the beloved is always
  in the mind of the lover.
He does not forget it even for a moment.
_{Kabir, as quoted in Philosophy of the Masters, Vol. I}
