The emotion of being happy; joy is happiness according to a mobile dictionary. [That meaning of happiness is way too precise yes but I like it like that as I don't like too much formalness really]. To be happy doesn't have to be how far neither does it have to be how well. It is just being happy irrespective of how it comes into being.
The state of happiness comes for people based from different ways. In other words, what makes me happy may not be what makes you happy. What makes a good person happy is quite different from makes a bad person happy. A good person would be happy because s/he helped five old persons to cross to the other side of the street in one day whilst a bad person would be happy because he beat a fellow to stupor at a bent road in the darkly time of the day and left him in the gutter for dogs to lick. The examples (are endless and they) pounce within good and evil. And it is funny either could fetch people happiness. This shows the influence of selfishness or lack of true love and care about the fellow man. True love, selfishness and fellow-man notions are not the subsidiaries I want to consider here today, what I am considering is HOW not to make happiness bring others sadness.
I heard someone say, "that is rubbish, that is not possible." Well maybe the person is right. But the person is definitely wrong when happiness is INTENTIONALLY used to make others, (friends or enemies) sad. So, this whole long explanations rally around our intention during our happy moments.
"We all want to help one another. Human beings are like that. We want to live by each other's happiness, not by each other's misery." - Charlie Chaplin
In furtherance, to hurt others needn't come from your doings I must tell, if you have been hurt before through any means by your friends or by your enemies, you don't need to try and leverage on your (a) scarce resource, happiness, in other to pay the person back. That is not helping you, not helping anybody and not helping the universe. It is all wasted effort when you'd be thinking you've achieved. You could of cause use your happiness to make someone feel paid back in the coin paid you. You would feel you have done that and the receiver would feel you have done that and no goodness is out of that as default. It is all far from it. Anything you do, such as exhibiting happiness, with the intent to hurt or harm, is not radiating positive energy but negative. It is not helping. It is being selfish and not thinking things through twice selflessly.
At this juncture, I would as well need to add that there is no how you'd try to manage your happy moments and someone would not be hurt by it. Understandable? As "Whether you do good or do bad people would always talk." So how do we do it then? It is simple and right. It has to do with the mind. The first thing is being conscious even when not. It is having a free mind at all time. How? By 'defaulting' loving all having forgiven all already even before harming you. With that, even if your happiness be taking a shot on your yellow Ferrari with your tongue out to your camera taking a selfie and posting it everywhere for people to see and your intent is clear, you have done proper but whoever gets hurt hence gets hurt at his or her own expense as the negative energy would only remain with such only really while you are good as gold. But a shot taken with your intent the otherwise, any hurt that comes from it is originated from you to the other person and then there is problem. These things are little things we tend not to care about but they determine the fate of the whole universe itself. I pray we all understand the more.
Finally, true happiness is a very hard currency to possess and to expend under the sun. The little you have, you'd please spend for goodness sake only and not for the otherwise through your intentions.
