It is being included in life and participating using one's abilities in day to day activities as a member of the community. It is being a part of what everyone else is, and being welcomed and embraced as a member who belongs.

Human beings, regardless if they happen to have a disability or not, have basic needs that must be met in order to feel fulfilled. The basic needs of food, water and shelter are necessary for us to exist. It's also easy to see that when you don't eat right or exercise it can adversely effect your health and capacity to function in other areas of your life. Having meaning and purpose to what you do and who you are, provides inspiration. Feeling useless or doing things that are meaningless, decreases motivation and self-esteem.
