@Kamila Tonia sensation is kind of physical. it can be any type of input to the brain. like, physical touch, vision, ear (sound) , taste (👅 food), smell(nose) . emotion is like response created by the brain for any kind of situation. like anger, fear or joy. and it depends on sensations too, cause you need some kind of input to your brain to have those emotions. the brain reacts with some kinda hormone like Dopamine, Oxytocin etc. and feelings are actually your thinking + emotions. let’s say you visited a place long ago and you like the beach so much even this days when you think about it you feel happy. so here, your eyes got got the input from nature ( got some sensation ), your brain says: I like the color of water and breeze ( that made you emotional) and when you think about that scenario your memory creates feelings ( memory of your emotions) … but in the end all are connected to our monkey mind ( brain ) . we can say sensation, emotion and feeling are interconnected. not so different but they help each other to realize they exists.
