Hello every one I have come far digesting the content of the master key system but I need a clear cut explanation on how to practice part 21 of the master key system:

For your exercise this week,concentrate on the Truth.Try to realize that the Truth shall make you free,that is,nothing can permanently stand in the way of your perfect success when you learn to apply the scientifically correct thought methods and principles.

Realize that you are externalizing in your environment,your inherent soul potencies. Realize that the Silence offers an ever available and almost unlimited opportunity for awakening the highest conception of Truth.Try to comprehend that Omnipotence itself is absolute silence,all else is change, activity limitation. Silent thought concentration is therefore the true method of the world within reaching, awakening and then expressing the wonderful potential power of the world within.

I understand concept of truth as explained in the previous chapter of the book but I am just trying to be thorough with the practice
