Suffering
I have my own experiences of sufferings and miseries, and after pondering over them a good deal I have now come to the conclusion that suffering and disease are the boons of Nature in disguise which helps deliverance from the effects of samskaras (impressions, grossness). When one is cleared of their remnants, spiritual progress goes on unabated, provided one's mind is inwardly inclined towards it. None is required to give up the normal activities of life connected with his worldly living, but needs only to be busy along-side with it for the attainment of That which is finally to be attained.
