THE last lecture dealt with the ineffable intuitive experience which the sages of the Upanishads regarded as absolute and ultimate in nature. The Upanishads, however, indicate no definite method for arriving at the perception of this truth. It is made clear that the pathway consists not in erudition or scholarship, and that it is not traversed by any sharpness of intelligence. The truth is such that it cannot be conceived by the human mind or described by language. One of the fundamental conditions of attaining it is the complete elevation of the moral life, including the absolute control of all passions and desires, the abandonment of worldly ambitions and hopes, and the attainment of an unruffled peace of mind. But the dawning of the supra-consciousness which can reveal this truth does not, even so, depend entirely on our own efforts; there is something like divine mercy that must be awaited. This self can only be realized by those to whom it reveals itself. The perfecting of our moral life is a prerequisite; but no method deliberately and consciously pursued is sufficient to bring us all the way into the full realization of the highest truth. In at least one or two of the Upanishads indications of a There are ample literary evidences that from very early times--from at least 700 or 800 B. C.--people were in the habit of concentrating their minds on particular objects and thereby stopping the movement of the mind and the senses and achieving wonderful, miraculous powers. It is difficult to say how the ancient Indians discovered this mode of mental control. But it seems very probable that as at first practised it did not form a part of any metaphysical system of thought but was simply the practise of mental concentration and breath control for the sake of the resulting peace and quietness of mind, as well as of the miraculous powers which could be achieved thereby. The powers of hypnotism, or mesmerism, seem to have been very well known in ancient India and were also included among the powers that could be derived from the yoga practices. A story is told in the Mahabharata (13.40) that Many other stories, illustrating the various kinds of miraculous powers of yoga, might be repeated. But let us turn to a consideration of the principal use of the yoga practices for the spiritual enlightenment, the ultimate and absolute freedom of man, as described by Patanjali, the great yoga writer of about 150 B. C. Patanjali not only describes the principal yoga practices, but he gives a philosophical basis to the whole system and indicates, for the first time, how yoga may be utilized for the emancipation of man from the bondage of his mind and senses. It was explained in the last lecture that the sages of the Upanishads believed in a supra-conscious experience of pure self-illumination as the ultimate principle, superior to and higher than any of our mental states of cognition, willing, or feeling. The nature of this principle is itself extremely mystical; many persons, no doubt, are unable to grasp its character. It has been shown that, even in the days of the Upanishads, it was recognized to be obscure, and that the sages were never tired of saying that it could neither be perceived by the eye nor conceived in thought; but that, nevertheless, the sages believed in its existence as the ultimate being and not as an experience of ecstatic feeling or any other kind of transient If we ask ourselves what we understand by "I," we shall all find that, though it is in the most constant use, it is also the obscurest word in all our dictionaries. About the meaning of the word, in one sense we can never doubt; for there is no person who can ever doubt whether he is himself or another person. But when we try to understand what it definitely and actually means, it appears to be one of the most elusive of words. It certainly cannot designate merely our bodies; nor does it mean any particular idea or feeling of a temporary character. So we have to admit that while we all understand what it means we cannot define it. This is not the place to enter into all the recondite philosophical discussions to which the problem of the nature of the self has given rise. But some attempt must be made to explain what the Indians understood by the immortal and unchangeable self. Some believed this self to be the same in all persons, while others believed it to be many; but the conception of its nature was more or less the same in most of the systems of Indian thought. It was pure, contentless consciousness, altogether different from what we understand by idea, knowledge, or thought. Our thoughts and feelings are changeful; but this mysterious light of pure consciousness was changeless. The ultimate aim of the yoga processes (as of most of the Indian systems of thought) is to dissociate ourselves from our sensations, thoughts, ideas, feelings, etc., to learn But with the Indian sages this doctrine of a transcendent self was not merely a matter of speculative philosophy. For philosophy came to them much later than the actual practice of the liberation of this true self from the bondage of the association with all our so-called psychical states, ideas, feelings, emotions, images and concepts. It is very difficult for a Western mind of today to understand, or appreciate, the minds of the Indian seers. They felt a call from within the deep caverns of their selves--a call which must have started from a foretaste of their own true essence--which made all earthly pleasures or hopes of heavenly pleasures absolutely distasteful to them. They could feel satisfied only if they could attain this true freedom, their true self. To appreciate their experience at all one must, in imagination, take a long jump backward of about twenty-five centuries and across the waters of the Atlantic and the Indian oceans, and picture to oneself the valley of the lofty snow-capped peaks of the Himalayas looking high up to the infinite of the heavens and, far beyond, the peaceful groves and cottages where the innocence and forbearance of man had endeared him to trees and beasts alike, where no other sounds disturbed the serene forest-dwellers than the breezy rustling of the lofty Sal trees and the grovy palms. The necessities of the men who dwelt there were few. They often wore clothes made from The problem of how to become free naturally raised the question as to who is to become free and from what. The logic of the yogins is irresistible. It is the self which has to become free; in fact it is always free. The self is the ultimate principle of pure consciousness, distinct from all mental functions, faculties, powers, or products. By a strange, almost inexplicable, confusion we seem to lose touch with the former so that we consider it as non-existent and characterize the latter with its qualities. It is this confusion which is at the root of all our psychological processes. All mental operations involve this confusion by which they usurp the place of the principle of pure consciousness so that it is only the mind and the mental operations of thought, feeling, willing, which seem to be The mind lives by its activities of sensing, perceiving and conceiving. It creates illusions and hallucinations, revives past experiences in memory, and sometimes passes into a state of sleep in which it creates dreams. If the movement of the mind could be entirely stopped, its disintegration would be effected. The process of yoga consists in so controlling the activity of the mind that it ceases to pass through its different states. The cessation of all mental states is yoga. These mental states as they rise and pass away are not altogether lost. They continue in the subconscious mind as impressions which are revived by proper excitations. As they are thus revived and repeated, and return to the subconscious, the impressions become strengthened, growing more and more powerful and more likely to occur as conscious states. Thus, for example, when we once devote ourselves to making money and to enjoying the comforts it can procure, we become more and more deeply absorbed in It is easy to see that no one will think of destroying his mind unless his desire for the absolute freedom of the spirit becomes so great that all the activities of the mind, all his sense-enjoyments, all his thoughts and feelings, lose all interest for him and appear to him to be entirely valueless. This disinclination to all worldly things, called vairagya, is the first thing which leads the yogin to seek the way of yoga to deliver himself forever from all mundane experiences. The seer is as sensitive as the pupil of the eye. Just as a speck of dust, which passes altogether unnoticed on any other part of the body, causes great pain when it gets into the eye, so the suffering, which is absolutely unnoticed by the ordinary person, is felt keenly by the seer. All ordinary pleasures appear to be distasteful to him. There is nothing in anything worldly that can give him any satisfaction. He is in that mood in which he is dissatisfied with them all and wishes to shun them. Such a state of mind cannot be produced unless the mind has risen to the highest plane of moral elevation. Unless the mind is made absolutely pure there cannot be any steady disinclination toward worldly things.YOGA MYSTICISM
