Q: You have said that most people do not find it difficult to bear the state of emptiness without any activity in the inner being. Then why do I find it difficult?
A) Most people means most who have the tendency or will to Yoga, for silence of the being is the first natural aim of the Yoga. You and some others do not find satisfaction in it because you have not overcome the vital mind which wants always some kind of activity, change, doing something or something happening. The eternal immobility of the silent Brahman is a thing it does not relish. So when emptiness comes, it finds it dull, inert, monotonous.
There is no necessity of explanation. Your mind creates problems and difficulties where none really exist. There is always the idea behind that passive peace is an undesirable thing. On the contrary it is the state of the silent Impersonal and an essential element and sure basis of the mukta condition and one can always rest in it whenever necessary with advantage.
