The fire is burning. You can see its light at a distance, but you cannot feel its warmth when you are away from the fire. Go near the fire. You will enjoy its warmth in winter. Even so, you can understand ‘sat’-aspect through the study of scriptures, but you can actually feel the bliss-aspect if you approach Brahman through constant meditation and if you realize the Self through direct intuitive perception.
Those householders who are endowed with dispassion and who are practicing daily meditation are not affected when they lose their near and dear ones or property. From all these you can clearly understand that pain and pleasure are mental creations only.
When the mind is attached to the body, there is pain. When the mind is withdrawn from the body there is no pain.
