Answer
There is an important distinction between enjoying the senses and seeking sense gratification.
The spiritual world is full of beauty and unlimited enjoyment. There are wonderful forms, fragrances, sounds, tastes, and all varieties of transcendental pleasure.
The difference lies in the purpose.
In the material world, the desire is, "I want enjoyment for myself."
In the spiritual world, the desire is, "I want to please Kṛṣṇa."
The devotee gratifies Kṛṣṇa's senses, and Kṛṣṇa, in turn, mercifully satisfies the devotee's senses.
The devotee never independently seeks personal enjoyment.
Every happiness experienced in the spiritual world is understood to be prasāda—the Lord's mercy.
Here, we usually think of prasāda only as sanctified food.
In the spiritual world, however, every form of enjoyment is understood as the Lord's mercy.
Another important difference is that in the material world one feels, "I have earned this enjoyment."
That mentality is called fruitive consciousness.
In the spiritual world, no one thinks that way.
No one claims to have earned anything.
Everything is joyfully accepted as Kṛṣṇa's loving gift.
