What is the meaning of complete dedication?

My Sunday Scripture 2009.11.8

Jesus sat down opposite the treasury
and observed how the crowd put money into the treasury.
Many rich people put in large sums.
A poor widow also came and put in two small coins worth a few cents.
Calling his disciples to himself, he said to them,
"Amen, I say to you, this poor widow put in more
than all the other contributors to the treasury.
For they have all contributed from their surplus wealth,
but she, from her poverty, has contributed all she had,
her whole livelihood."

Mark 12:41-44

My Reading Notes:
-------------------

Actually this is a very simple idea. The meaning of life
itself is not for the self. The meaning of life is to
dedicate, no matter who you are: no matter you are a
cat or a dog or a plant, your life is meant to the others.
Life itself is a chain, only those who could see the meaning
of life in the whole could understand the meaning of
dedication.

For deditcation, there is only one kind of dedication:
complete dedication. The meaning here is not how much
you could afford to pay God, but whether you could see
that you have only one life, and the purpose of that
life is for you to use it: Use it on the planet, not
for self indulgence or lazy sleeping.

Those who could see the meaning of life, is blessed.
