Those who are artists, overtaken by the beautiful creation, should better look to the beautiful face of the Lord for complete satisfaction. The face of the Lord is the embodiment of beauty. What is called beautiful nature is but His smile, and what are called the sweet songs of the birds are but specimens of the whispering voice of the Lord.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 1.11.26, Purport

The holy name is by nature eternal and full of knowledge and bliss. By the holy name’s mercy, a living entity revives his spiritual consciousness. Sri Krishna, who is the reservoir of all transcendental pleasure, manifests in a heart filled with simplicity, before eyes that have been fully spiritualized, on a tongue inclined to His service, and in an ear inclined to hear krishna-katha. The holy name manifests in those senses that are engaged only in pleasing His senses.

Padma Purana, Prabhasa-khanda

Attaining the Supreme Lord is the medicine to cure the suffering soul. That medicine fills the taker with transcendental bliss.
Sri Vishnu Purana 6.5.59

When one understands that the Supreme Personality of Godhead and the individual spirit souls are eternally distinct entities, then he may become qualified for liberation and live eternally in the spiritual world.
Shvetashvatara Upanishad 1.6

O best of the Kurus, the earth continued as follows: “Although in the past great men and their descendants have left me, departing from this world in the same helpless way they came into it, even today foolish men are trying to conquer me.
