The idea of ​​84 āsanas, which is often found in yoga texts, is based on the worship of 84 nātha–yogis. Each of these 84 nāthas is responsible for the evolution of one lakh of living beings (100,000). When you follow the yoga path, you develop the psychophysical, spiritual purity in yourself, that you radiate into space. By doing your practice you help not only yourself, but also your close ones. Souls reincarnate in different forms until they become perfect yogis, the symbolism of 84 āsanas is based on this principle. The most important thing here is to understand that āsana is not just a physical process, but also a psychophysical one. The purpose of many āsanas is to be able to stay stable in the position of siddha (siddhāsana). Generally, it is the ability to stay in a meditative posture for three hours, to hold it easily, so that you can meditate, remaining in the position, on something sublime and pure in it.
