As we look deeper into the workings of the law of karma, we begin to see that one reason we go on doing what we do not experiences the repercussions of our thoughts and actions, would we ever allow them to lead us to suffering? If we put our hand into a fire, we immediately experience pain, so we do not repeat the action. But just imagine what happen if our nerves were not functioning? We might leave our hand in the fire- we might even go on doing so our hand burned away. This is physical plane, but it is the same at the spiritual level. Our spiritual nerves have been dead end to such an extent that we fail to understand where our thoughts and deeds are taking us. We forget that while the wheels of the law may grind slowly, they grind exceedingly fine. In the Buddhist scriptures we read:-

So long as an evil deed does not bear fruit

The fool thinks that it is like honey,

But when it bears fruit, then the fool suffers grief.

An evil deed, like newly drawn milk, does not sour,

Smoldering, like fire covered by ashes it follows the fool.
