It's a misconception that Purity and Sanctity are only prerogatives of saints, and are not absolutely necessary for normal people. In my view, leading ultra-pure life with purity in thoughts, words, and actions surely define one's character. What's more, the Purity is an essential requisite and a most important criterion for defining a normal person. The disrespect or disregard to Purity and Sanctity is only the deviation from normal behavior IMHO. Strive to lead an ultra-pure life, in your thoughts, words and actions - always!
