"Mind your own business" is a good rule. It would probably be safe to say that more than half of the evil in the world is due to well meaning busybodies who just cannot refrain from interfering. Needless to say, such people never have harmony or success in their own lives, for it is an invariable rule that those who mind their neighbors' business, neglect their own.
All this is true, and we cannot recollect it too often, but in a deeper sense it is equally true that what we mind--what we give our attention to--always does become our business, and sometimes our destruction. When you interfere mentally in any condition, you involve your life in it to the extent of that interference. When you take sides mentally, or become emotional concerning the matter, and still more when you talk about it, and still more again when you do anything about it, you are making yourself a party to it and will have to take the consequences.
In other words, you cannot involve your thoughts in any subject without bringing the natural consequences upon yourself. You can call this involving yourself in the karma of the situation, if you like, but whatever you choose to call it, the fact will remain. To interferementally in any situation involves you in the consequences just as much as would a physical interference.
Of course, where it is your duty to concern yourself in any matter, you must do so constructively and spiritually--and then the consequences to you can only be good.
The Bible says, "he that passeth by, and meddleth with strife belonging not to him, is like one that taketh a dog by the ears" (Proverbs 26:17). If, when those around you are talking negatively about something or someone, you chip in with your contribution to the witches' brew, you are taking a strange dog by the ears--so look out! If you get emotionally tangled in what is not your affair, through indignation, self-righteousness, hatred, or otherwise, you have seized the dog again, and you will have to pay for it. If you rush about interviewing, telephoning, busying yourself in the same spirit, you have tackled the dog once more--and he will bite! And even to think negatively concerning such matters in the secretchamber of your own heart, will bring you proportionate and natural punishment.
It is always right to think rightly about any person or situation, and if you do this many opportunities will come to you to help people practically too, without any breach of the law we have been considering, and without coming near the dangerous dog.
