Science is now documenting that it's not the objects of meditation that are important, it's the process of paying attention to them - the attending - that actually influences the organism in a whole range of different ways. The brain changes significantly enough to impact thought, emotion, and other biological functions. Today, people recognize that they're not going to find well-being from the outside, or from a pill; they're going to find it by looking inside. All the suffering, stress, and addiction comes from not realizing you already are what you are looking for.
