Zed pointed out that ‘yoga’, which had come to mean in the West as ‘modern postural yoga’, was actually a mental and physical discipline by means of which the human soul united with universal soul.
Zed noted that asanas (postures and exercises), which found references back to the Upanishads, were for the purpose of meditation. The body had to be kept in suitable posture so that seeker could meditate with straight spine, and with stomach and lungs not restricted; like Padmasana.
Zed further said that even hatha yoga, with its postures and exercises, prescribed eight stages: yama, niyama, asana, pranayama, pratyahara, dharana, dhyana and samadhi. The highest form of yoga, sometimes referred as raja-adhiraja-yoga, was said to free our minds from fear, lust, melancholy, anger, jealousy and greed.
Zed stated that even Oxford Concise Dictionary of World Religions defined yoga as: The means or techniques for transforming consciousness and attaining liberation...through yoga it (mind) can be focused, one pointedness developed, and higher states of consciousness experienced...Patanjali states the goal of yoga to be quite simply the 'cessation of mental fluctuation' which results in higher levels of consciousness or absorptions and the purification of the self.
