It is in the four attributes here emphasised that the true nature of mind in its underivability and superiority to all nature first becomes clear. All that we have so far considered under the name of mind is only preliminary and leads up to this. All reality of external things is of little account compared with that of the mind. It does not occur to any one in practice to regard anything in the whole world as more real and genuine than his own love and hate, fear and hope, his pain, from the simplest discomfort due to a wound to the pangs of conscience and the gnawings of remorse—his pleasure, from the merest comfort to the highest raptures of delight. This world of feeling is for us the meaning of all existence. The more we plunge ourselves into it, the deeper are the intricacies and mysteries it reveals. At every point underivable and unintelligible in terms of physiological processes, it reveals itself from stage to stage as more deeply and wholly unique in its relations, interactions, and processes, and grows farther and farther beyond the laboured and insufficient schemes and formulas under which science desires to range all psychical phenomena.
