A person may lose hope in his profession or trade. For instance he may have gone to a singer to take singing lessons for one or two months, or for one or two years, and then he may think, "I am not getting on with this, I should stop singing. I believe I have no voice." Or he may think, "I am not getting on in my business. I cannot make it a success, I should give it up." The ill is not changing of profession or business, but giving up altogether. If the person thinks, "Now I wish to be a poet", and becomes a poet, then he is not hopeless; or if he thinks, "Now I wish to compose", and old age the hurt of the heart may cause hopelessness. This shows us how careful we should be not to hurt the heart of another and not to let our own heart be hurt. In India we are most careful of this; diljoi, not to hurt the heart of another is taught as the greatest moral: not to hurt the heart of the parent, of the friend, even of the enemy. Also our own heart must be protected by forts around it.
