Never allow any unnecessary or vain thought to occupy your mind. This is more easily said than done. You cannot make your mind a blank all at once. So in the beginning try to prevent evil or idle thoughts by occupying your mind with the analysis of your own faults, or the contemplation of the Perfect Ones.
H. P. BlavatskyEverything in the Universe, throughout all its kingdoms, is conscious: i.e., endowed with a consciousness of its own kind and on its own plane of perception.
H. P. BlavatskyReflect upon the defects of your character: thoroughly realize their evils and the transient pleasures they give you, and firmly will that you shall try your best not to yield to them the next time.
