You should realise that it is not possible for anyone to know in what form, in what situation, at what time and in what circumstances the Lord appears to man to teach him how to get rid of his bad thoughts, bad qualities and bad actions. Therefore, you must make every effort to sanctify your life by good thoughts and good actions. This is true sadhana (spiritual discipline). Sitting in so-called meditation without getting rid of your bad qualities is utterly valueless. It is an 'artificial' exercise. What you should do must come from the heart.
