五識

The five (sa) parijñānas, perceptions or cognitions; ordinarily those arising from the five senses, i. e. of form-and-color, sound, smell, taste, and touch. The 起信論 <Awakening of Faith> has a different set of five steps in the history of cognition;

(1) 業識 initial functioning of mind under the influence of the original 無明 unenlightenment or state of ignorance;

(2) 轉識 the act of turning towards the apparent object for its observation;

(3) 現識 observation of the object as it appears;

(4) 知識 the deductions derived from its appearance;

(5) 相續識 the consequent feelings of like or dislike, pleasure or pain, from which arise the delusions and incarnations.
