tendency to conceiving philosophical problems in a clear and unambiguous manner is an important feature of Sanskrit thought, but from the ninth century onwards, the habit of using clear, definite, and precise expressions, began to develop in a very striking manner, and as a result of that a large number of technical terms began to be invented. These terms are seldom properly explained, and it is presupposed that the reader who wants to read the works should have a knowledge of them. Anyone in olden times who took to the study of any system of philosophy, had to do so with a teacher, who explained those terms to him. The teacher himself had got it from his teacher, and he from his. There was no tendency to popularize philosophy, for the idea then prevalent was that only the chosen few who had otherwise shown their fitness, deserved to become fit students (adhikārī) of philosophy, under the direction of a teacher. Only those who had the grit and high moral strength to devote their whole life to the true understanding of philosophy and the rebuilding of life in accordance with the high truths of philosophy were allowed to study it.
Another difficulty which a beginner will meet is this, that sometimes the same technical terms are used in extremely different senses in different systems. The student must know the meaning of each technical term with reference to the system in which it occurs, and no dictionary will enlighten him much about the matter[1]. He will have to pick them up as he advances and finds them used. Allusions to the doctrines of other systems and their refutations during the discussions of similar doctrines in any particular system of thought are often very puzzling even to a well-equipped reader; for he cannot be expected to know all the doctrines of other systems without going through them, and so it often becomes difficult to follow the series of answers and refutations which are poured forth in the course of these discussions. There are two important compendiums in Sanskrit giving a summary of some of the principal systems of Indian thought, viz. the Sarvadarśanasamgraha, and the Sadddarśanasamuccaya of Haribhadra with the commentary of Gunaratna; but the former is very sketchy and can throw very little light on the understanding of the ontological or epistemological doctrines of any of the systems.
