If you trace the entire chain of psychology and find out the root of all evils you will stop at Love. Since this emotion has many contexts and connotations we may write it off this as some fluffy stuff. But Love the most powerful emotion and this is the driving force. If you deeply notice most people crave for this emotion in different forms – appreciation, praise, connection, recognition, friendships, relationships, etc. This is basic human nature and need.
If some one has not received/experienced this emotion during early childhood then this will result into all issues. Actually there are no “bad people”. These “bad people” are simple ones who not fortunate enough experience this deep emotion. All the criminals, sadistic and narcissist people have missed this emotion. Lack of this results into hatred and fear. Out of fear and hatred all evil actions starts.
On the contrary and positive side, all amazing things happens with the emotion of love. We may have different names for this – passion, mission, interest, happiness and life. All major and good transformations resulted out of deep love.
Love is the short cut cure to all issues. Starts with self love. Observe yourself and others around you will get the key.
