Vivekananda in Raja Yoga is divided into eight stages, grades and stretches of the trail should be as follows:
1) Yama.
2) Niyama.
3) Asana.
4) Pranayama.
5) Pratyâhâra.
6) Dhârâna.
7) Dhyana.
8) Samadhi.
Yama is not kill or steal or lie or not to receive gifts and fornicate. Niyama equals purity, contentment, honesty, study and complete surrender to God. Asana is the posture or position that has placed the retreatant. Pranayama is the government regulation or encouragement. Pratyâhâra is disengaged from the senses of the objects of sensation. Dhâranâ to set the mind in a certain order. Dhyana, meditation equals. Samadhi is the state of ecstasy or superconciencia. Yama and Niyama are moral disciplines without whose fluency is useless and even delivered to the harmful practices of Raja Yoga. Once firmly established Yama and Niyama, can get some retreatant result of practice, but they will not get positive result. The damage has not retreatant absolutely anyone, man or animal or plant or mineral by thought, word or work. To reach the higher grades require some physical and mental daily practice, so it is necessary to put in a position that can endured a long time without fatigue. Of course it is not possible to indicate specific positions for all retreatant, because that is comfortable for some is uncomfortable for others, and everyone has to assume that best suits enella not bother to keep all the time throughout the year. Nerve currents take new direction and set a new tone vibration, so as to transmute the whole physical constitution. Most of the activity is located in the spine, so the only precondition in the position to be adopted must be that chest, neck and head is kept upright in a straight line without the slightest shift in the column vertebral and letting the weight of the trunk rests on the ribs. We can not have very lofty thoughts, with the sunken chest and head bowed.
This degree of Raja Yoga is something similar to the Hatha Yoga which specifically deals of health and vigor of the physical body. We have nothing to refer to Hatha Yoga in this book, because its practices are very difficult and can not learn in a day or tend to the improvement spiritual. The practice or exercise called the purification of the nerves are rejected by some scholars do not consider it proper to Raja Yoga, but as a Swami Vivekananda - Raja Yoga 11 Sankara as the authors admit in their comments and advised andalusia Upanishad Svetasvatara, as follows: "When Pranayama remove all scum of the mind is fixed on Brahman. First they purify the nerves and then you can practice pranayama. At the end, the top right window of the nose with thumb and draws air through the window left, and without interruption is the lid with your thumb the left window to exhale air from the right. Then flip the window to be inspired by the right and left exhale on the right blocking the left. "Repeat this exercise alternating five times in the following hours day: before dawn, at noon, when the sun and midnight. "After one month of continuous practice respiratory nerves are purified and may proceed to the exercise of Pranayama. " The practice is absolutely necessary. Much as we hear or read about the Raja Yoga, is not a step forward without practice. Never a good thing to learn that I personally experienced, and theories alone hinder rather stimulates practice. The first difficulty encountered in the practice of Raja Yoga is a body sick, since without full health will be in vain attempt to practice and so should be very careful about diet and comply fully with the laws of physical and mental health, not forgetting that health is one means of reaching the end. If health to be returned to the animal kingdom stage where the mind is embryonic and instinctive. The second difficulty is the question. Always doubt what we see. The man did not can rely on mere words to strive for a long and well, who in turn first hear about the practice of Raja Yoga, doubting the truth of what is said, but if you undertake the exercises will soon get a glimpse of the truth stimulate and encourage him to continue with hope of venture success.
