No one likes to drink poison with the idea that antidote is available
handy.Likewise,atonement should not be considered an excuse all the
time to commit sinful actions.What use is the atonement if we keep on
committing sinful actions? Atonement is a chance to repent past sins
and recover the soul from transmigrating to variety of bodies.
Otherwise it's the elephant story only. Taking bath in the river
nicely and then smearing the body again with dirt when back to
shore.Both good karma and bad karma are sinful becoz it binds one
back2repeated birth&death.
