Remember, whatever actions you do

Remember, whatever actions you do, the corresponding qualities will develop and will remain part of you.

Perform your duties always

Perform your duties always,  Never hold the vanity of doer. 

Believe always, that God is the doer, and offer the results to God always.  

Then the deed will not bound you and danger of births will not hinder you.

Who sows surely reaps it's fruits

Who sows surely reaps it's fruits, why should other suffer with anxiety?

So meditate on it regularly.

Know that which is knowledge incarnate, or Supreme pure Consciousness or Blissful joy -- that is my true nature. So meditate on it regularly.
