What is life?

This morning, I was wondering what is life? What does it mean? What is the definition? etc. So I searched the definition of life on Google and found following results.
Definition of life:

• a characteristic state or mode of living; "social life"; "city life"; "real life"
• the experience of being alive; the course of human events and activities; "he could no longer cope with the complexities of life"
• the course of existence of an individual; the actions and events that occur in living; "he hoped for a new life in Australia"; "he wanted to live his own life without interference from others"
• animation: the condition of living or the state of being alive; "while there's life there's hope"; "life depends on many chemical and physical processes"
• the period during which something is functional (as between birth and death); "the battery had a short life"; "he lived a long and happy life"
• the period between birth and the present time; "I have known him all his life"
• the period from the present until death; "he appointed himself emperor for life"
• a living person; "his heroism saved a life"
• liveliness: animation and energy in action or expression; "it was a heavy play and the actors tried in vain to give life to it"
• living things collectively; "the oceans are teeming with life"
• the organic phenomenon that distinguishes living organisms from nonliving ones; "there is no life on the moon"
• biography: an account of the series of events making up a person's life
• a motive for living; "pottery was his life"
• life sentence: a prison term lasting as long as the prisoner lives; "he got life for killing the guard" 

Well it's a complex topic and it's not easy to define Life specifically. I'll post my thoughts about life and what does I think of life. I am a spiritual person, so my thoughts would be much related to spiritual aspects of life.
Here are the meanings of life from www.biology-online.org:

Life
Origin: as. Lf; akin to D. Lijf body, g. Leib body, MHG. Lp life, body, OHG. Lb life, Icel. Lf, life, body, Sw. Lif, dan. Liv, and E. Live, v. See live, and cf. Alive.
1. The state of being which begins with generation, birth, or germination, and ends with death; also, the time during which this state continues; that state of an animal or plant in which all or any of its organs are capable of performing all or any of their functions; used of all animal and vegetable organisms.
2. Of human being: The union of the soul and body; also, the duration of their union; sometimes, the deathless quality or existence of the soul; as, man is a creature having an immortal life. She shows a body rather than a life. (Shak)
3. (Science: philosophy) The potential principle, or force, by which the organs of animals and plants are started and continued in the performance of their several and cooperative functions; the vital force, whether regarded as physical or spiritual.

Well, all of the above was just the definition of life rather than the philosophy of life. I'll put my random thoughts about "What is life?" in multiple posts because this topic is complex as well as broad in its meaning. And also will post whenever I'll have random thoughts of "What is life?". In next post regarding this topic I'll write my thoughts with some examples.
