If you are interested in buddhism or other spiritual paths, try them out. Just reading about a spiritual path is like choosing a car by reading about it. You need to try it out. And meditate frequently; meditation is pretty important. Otherwise you won’t be able to understand what is really being said at times.
If you completely understood living a life full of compassion, then you wouldn’t need to ask the origin of it. Compassion is good enough on its own. It is only your mind that seeks answers to such questions.
But sometimes the mind needs to be put to rest. Perhaps you need an answer to this question so you can stop wondering and start just being compassionate.
I would say that compassion arises when you begin to see your Self
(not your ego but the vibrant emptiness within you) in everything you meet in the moment. Form is emptiness and emptiness is form. Compassion is the emotion of the whole Cosmos when it recognizes itself. Compassion is definitely a cosmic feeling made relevant to the moment.
