Not to rid my life of speaking the truth when that is a statement that might be negative. But to rid my life of an attitude of negativity.
That includes conversations and thoughts, words I speak, conversations I encourage by my interest, attention I give to my thoughts and many other things.
Right now I'm in the process of noticing the extent to which negativity is present in my life. It feels harsh and painful but gentle, good and full of peace. It has all the hallmarks of the spirit of truth at work.
