Quote from : Satipaṭṭhāna: The Direct Path to Realization Book

The advantages of developing absorption concentration are not only that it provides a stable and receptive state of mind for the practice of insight meditation. The experience of absorption is one of intense pleasure and happiness, brought about by purely mental means, which thereby automatically eclipses any pleasure arising in dependence on material objects. Thus absorption functions as a powerful antidote to sensual desires by divesting them of their former attraction.
