Do you love to do car wash?
Do you love to clean up your car frequently?
What will happen if you are not cleaning up your car constantly?
Your car will cover by a layer of dirt, dust, bird shit and others.
The longer you are not going to clean up your car, your car will become more dirty and more effort needed to clean your car.
Its apply the same in our spiritual practice. We need to keep walking our path diligently, cleanse up our dirt in our mind, constantly repentance for wrong doing and committed not to repeat.
