The individual needs to feel good why they share or the individual needs to feel bad why they're selfish, these are the reasons why Self is experienced in the 3Dimension Illusion/Reality.
There is always a reason for people's behaviour, reason gives intent and intent gives behaviour a reason to be.
People who believe to be selfless is not to have a reason to give. This behaviour is a camouflage to hide their evil behaviour, give it time and their true intentions will be made known.
Negative people/hu-man beings are unable to connect the dots why they speak so much shit and believe it makes sense.
Hidden behaviour is not detected with the eyes, it is detected through feelings.
