* '''साक्ष्य (Evidence):''' Evidence is the knowledge that is obtained from other persons, those whose experience we consider trustworthy. For example, for this, parents and gurus are considered to be the trustworthy people. Books written by scholars, contains references and hence they are considered trustworthy. Man cannot acquire knowledge in every field on the basis of his own experience. Therefore, for knowledge in these areas, he should consult the experts of these areas. For this reason religious the articles of religious books are considered authentic and in science, scientific literature is considered authentic. People thus rely on the evidence given by trustworthy scholars when they do not have the knowledge by themselves and since this is not in the direct experience of the person, it is termed as Apratyaksha or Indirect knowledge.<ref>Sharma, Ramanath.

Often, when there is a debate going about a term, we see why the debaters take that term in different ways, arguing in vain. So, first of all from the point of view of tarka it is necessary that we define the problem to be considered so that there is no pointless debate. For example, different people have different meanings of the word Ishvar and any debate about it is useless and unending. Now if the meaning of the word Ishvara is defined, any further debate made around this definition renders the subject matter useful. Thus, tarka is that exploration of truth in knowledge.  It discriminates between the truth and untruth in an investigation.
