Karma

As we saw in earlier post, For becoming karma yogi one needs to clean himself / herself. 

Why?

As we saw whatever actions we do are first manifested in our mind. (Rather whatever we have manifested in our mind gets into reality, many a time supported by our actions). But the thoughts we get in mind are influenced by our memory. And memory is populated by five senses and our actions. 

This sort of makes a vicious circle. And we get trapped into chains. There are only two ways to break the chain. 

(1) To make sure that our actions should not get stored into memory or 
(2) the memory does influence the actions that we take.

 First one is impossible. When we do any action, all (or some) of our senses are involved and hence they will result in a memory. 

The only option then remains is our future actions not be influenced by our memory. 

This is possible if our memory about the action is pure. 

What is a pure memory means that - the action was not conducted for ones selfish benefits.  It was conducted without any expectation of fruits and in that sense the action was pure.

Only in such cases the stored memory will not have any influence on the future actions. 

If every action conducted  is "pure" then it breaks the chain and a person can then attain freedom.

this is the very basic of karma yog. 

And hence it is said always to cleanse yourself.
