We are unable to realise God within us because we do not realise the soiled cover in which it is wrapped up. If our clothes get dirty, we change them because we are ashamed to appear in dirty garments. If our house is dirty, we clean it so that visitors may not get a bad impression of us. But when our minds and hearts are polluted, do we feel ashamed? Is it not strange that we should be so much concerned about the cleanness of our clothes or our homes, but are not bothered about the purity of our hearts and minds which affect our entire life? To purify our hearts and minds, the first thing we must do is to lead a righteous life. Our actions must be based on morality. Indulging in abuse of others or inflicting pain on them is not a sign of human nature. The evil that we do to others ultimately recoils on us.
