The progress of the universe is interlinked with the progress of man. Any amount of development in scientific, economic, social spheres will not be of much use without mental transformation. How can we bring about this transformation? It is by keeping in check one's passions and emotions. Since mental tension is more detrimental to man's health, one should learn the art of controlling his passions and emotions, which can cause stresses and strains. Man should make an earnest endeavor to lead a severe and pure life. He should realize the truth that troubles and turmoil are temporary like passing clouds. There is no scope for agitations to rise if one realizes this truth. One who realizes this truth will not allow his mind to be swayed by the passions of anger, cruelty, etc.
