As the imaginings of a person that is awake and engaged in acts, are due only to the creative power of the mind, after the same manner the impressions in a dream appertain only to the mind. A person with desire and attachment obtains those imaginings (in dreams) based upon the impressions of countless lives in the past. Nothing that impresses the mind once is ever lost, and the Soul being cognisant of all those impressions causes them to come forth from obscurity. Whichever among the three attributes of Goodness, Passion, and Darkness is brought about by the influence of past acts and by whichever amongst them the mind is affected for the time being in whatever way, the elements (in their subtile forms) display or indicate accordingly (in the way of images). After images have thus been produced, the particular attribute of Goodness or Passion or Darkness that may have been brought by past act rises in the mind and conduces to its last result, viz., happiness or misery. Those images having wind, bile, and phlegm for their chief causes, which men apprehend through ignorance and in consequence of propensities fraught with Passion and Darkness, cannot, it has been said, be easily discarded. Whatever objects again a person perceives in the mind (while wakeful) through the senses in a state of perspicuity are apprehended by the mind in dreams while the senses are obscured in respect of their functions. The Mind exists unobstructedly in all things.
