There are two experiences of emptiness: one spacious and liberating, and the other deficient and depressive. The subjective experience is definitely different and distinct for each of these kinds of emptiness. The presence of these two types of experience of emptiness could lead to much confusion and misunderstanding, especially when one reads the literature of existentialism or psychoanalysis and then contrasts it with the literature of Far Eastern philosophies and religions. – The Void: Inner Spaciousness and Ego Structure, Ch. 16
