Sadhana will disclose to you this identity. You calculate how much or how long you have done Sadhana and you are tempted to look down on another, whose record is less. You get no water however often you may dip and pull the basket up. Each vice is a hole in the bucket. Keep the heart pure, keep it whole.
All religions exhort man to cleanse the heart of malice, greed, hate and anger.
All religions hold out the gift or Grace as the prize for success in this cleansing process. Ideas of superiority and inferiority arise only in a heart corrupted by egoism. If some one argues that he is higher or that his religion is holier, it proves that he has missed the very core of his faith. Sadhana will reveal likewise, the unity in the fundamental teachings of all religions. It is of course a hard path, but it is a path that every one has to take now or later.
