The mystic, who virtually ceases his various bodily functions according to Patañjali's system of mysticism, tries to attain trance by these systematic modes of meditation and so forth. Thus, the mystic tolerates all sorts of tribulations in order to visualize the localized aspect of the Supreme Spirit. In other words, he does not care about what it may take, even if it means meeting with death, to realize his ideal, which has no equal in the universe. To underscore the validity of such mystics or devotees, the Personality of Godhead says in Bhagavad-gītā (6.22) that He does not consider anything more valuable than the attainment of that transcendental state: "It is the greatest gain. To be in that state means not to be perturbed by any distress, however heavy and intolerable it may be."
According to Patañjali's system, mysticism means perfect control of the mental plane with its various fickle inclinations. According to Patañjali, the transcendental state is to become free from sensuous activities and to attain the stage of perfection perceptible purely by the spirit soul. In such a state, the attention of the mystic never deviates from that spiritual achievement. The eightfold material perfections—such as aṇimā, laghimā, prāpti, īśitā, vaśitā, prākāmya, and so on—are concomitant in the attainment of perfection in mysticism, and are but indirect by-products of that process.
After attainment of one or two of the above perfections, many mystics fall into the trap of mental oscillation. In such a state, the mystic fails to attain to the highest perfection, namely, pure devotion to the Supreme Personality of Godhead. But the transcendental worker, or karma-yogī, has no such fear of falling down, for his attention is already fixed in the transcendental service of the Personality of Godhead. Thus, he does not need to enter separately into trance. For the karma-yogī, the mystic perfections manifest automatically due to the ever-increasing freshness of their object of attention, the Personality of Godhead. A mundaner is surely unable to realize how there can be so much transcendental happiness in the service of the Personality of Godhead.
