Selfless Love cannot be studied,
researched, analyzed, etc.  Just as we
cannot really study, research, analyze,
etc. God.  When we study, research,
analyze, etc., we use the mind.  The
mind is finite and limited.  God and
Selfless Love is infinite and limitless.  
Finite can never understand the
infinite.  The lower can never
understand the higher.

When we choose Selflessness, we
automatically and gradually start
cancelling bad Karma.  The more
Selfless we become, the more bad
Karma we cancel.

When we are selfish, we accumulate
more bad Karma on top of the bad
karma we already have.  We are not
cancelling or balancing existing bad
Karma, but we are adding more bad
Karma.
The most common excuse is that we
do not understand what Selfless Love
so we cannot choose to be Selfless.

We always want others to love us
unconditionally so we are not being
honest when we say we cannot or do
not know how to love others
unconditionally.  We even say we do
not understand Unconditional Love or
it is too hard to love unconditionally.  
We also say when we love
unconditionally, others will take
advantage of us.  We want others to
love us unconditionally but we do not
want to love others unconditionally.

Please be honest to ourselves.  We
are pretending not to understand
Selfless Love so we can remain
selfish.  We think we have more to gain
by remaining selfish.  Unfortunately
selfishness only guarantee self
destruction.  Anything we gain right
now is a temporary illusion.  All the
physical world achievements (fame,
fortune, etc.) are absolutely
meaningless.
