Life is the same thing as awareness (or at least human life is). For me, a person who is no longer aware of their surroundings (like someone who is severely brain damaged or someone who has Alzheimers' so badly that they don't know who they are anymore is really not alive. Of course, they are living creatures, but they are not alive in the sense of still being human. So my definition for human life at least is that you have to be aware of who you are and what your surroundings are.
Life is a series of intertwined choices we and others make as we occupy this spiritual realm on earth. What we do affects others; what the do affects us. It's all part of a bigger picture of which we are only allowed small glimpses at a time. We all have a role--we're all significant.
Do you mean definiton? My definiton of life is change. Things never stay the same. In order to grow, we have to keep moving. It took me awhile to realize that life is about change. It has not always been easy for me.
Life is about sacrifice. This is because people's lives are interrealted.There are many examples: mothers sacrifice for their children; soldiers scacrifice for their country. If people in the world are selfish and not willing to sacrifice, the world just won't progress.
