Extinguishment is Bliss
At one time Venerable Sāriputta was staying near Rājagaha in the Bamboo Grove, the squirrels’ feeding ground. There he addressed the mendicants: “Reverends, extinguishment is bliss! Extinguishment is bliss!” When he said this, Venerable Udāyī said to him, “But Reverend Sāriputta, what’s blissful about it, since nothing is felt?” “The fact that nothing is felt is precisely what’s blissful about it. Reverend, there are these five kinds of sensual stimulation. What five? Sights known by the eye, which are likable, desirable, agreeable, pleasant, sensual, and arousing. Sounds known by the ear … Smells known by the nose … Tastes known by the tongue … Touches known by the body, which are likable, desirable, agreeable, pleasant, sensual, and arousing. These are the five kinds of sensual stimulation. The pleasure and happiness that arise from these five kinds of sensual stimulation is called sensual pleasure.
