We should feel. We should be sensitive towards ourselves and all others. Our progress and happiness should not be the only priority. Others should also be happy. Happiness if shared, multiplies. Sorrow, if shared, decreases. Hence, both need to be shared. Express benevolence unconditionally, without expectations. It is worth it. Trust me.
Doubts…
Conscious mind creates doubts. It also creates fear of the unknown. It is the inherent characteristic of the conscious mind to create doubts and subsequent insecurity. Doubts are based on the level of consciousness. On a sunny morning, when basking in the warm rays, the conscious mind is sure that its morning and there is sunshine. But, a person who sleeps inside a blanket with curtains blocking rays from entering the room can never be sure of the situation outside his windows. His mind speculates. So, the available data and the level of consciousness creates the doubt.
