Krishna promised that He would protect the sadhus. Who are the sadhus? Those that are wearing ochre robes or those that hold Gita in their hands and preach are not sadhus. A sadhu is one who perceives unity in diversity. He will have unity of thought, word, and action. This is called education in human values, which is E-H-V. In my opinion, it is 3 H-V. It is the unity of head, heart, and hand. It is the combination of thought, word, and deed, which is the trinity of humanity.
