The Cauldron of Poesy lists a series of joys and sorrows which can rotate the metaphysical cauldrons within us, and unlock divine inspiration.
It reveals the Celts believed that to become a master poet, one needed not to renounce or try to escape this world, but fully embrace it, in all of its beauty and suffering. 

The listed divisions of joy that turn the cauldrons are; intimacy, health and prosperity after studying poetry, the wisdom after the creation of poems, and the ecstasy from eating the nuts of the nine hazels of the Well of Segais in the Sidhe realm, which the Salmon of Wisdom does in the Fenian Cycle. 

The divisions of sorrow that turn the cauldrons are; longing, grief, jealousy, and the discipline of pilgrimage to holy places.

Painting by Thomas Jones, 1774.
