It is very difficult for us now to attack the evil tendencies directly and to drive them out. We have given them space in our mind for a long time. They claim their place in our mind as their birth right. We can get rid of them only through the Pratipaksha Bhavana(The method of substituting the opposite through imagination; thus, fear is overcome by dwelling strongly upon its opposite, viz., courage) method, by transplanting them with good virtuous qualities. The evil qualities will die by themselves. Positive always overcomes the negative.
A Sadhaka cannot afford to forget this detailed living of divine life, and his whole life, at least in the beginning, should be characterised by restraint. He should restrain his tongue. Do not think that you can eat anything and meditate well. If a Sadhaka thinks that he can eat anything and meditate, he is deceiving himself.
