The Yoga Sutra, one of the six darshanas in the Hindu school of philosophy, is a set of 95 aphorisms written somewhere between 1,700 and 2,200 years ago by the Indian philosopher Patanjali. Thus we learn and practice Yoga, Pranayama, Meditation, Samadhi, Samyama, the Kundalini Kriyas, Chinese Alchemical Taoism and the Micro and Macrocosmic Orbits, VITRIOL and The Emerald Tablet of Hermes Trismegistus, The Grounding of Negative Energies, The Yoga Sutras of Patanjali, Raja Yoga and the Eighteen Classical Yogas of the Bhagavad Gita.

It is now, that our practice is developing to the point where saddha (faith), viriya (effort), sati (mindfulness), samadhi (concentration) and panna (wisdom) become firmly established. Patanjali still considers sense withdrawal (pratyahara) to be an outer limb while listing concentration (dharana), meditation (dhyana) and absorption (samadhi) as the inner limbs.

We have seen that Sankara does speak of a type of concentration upon the Self which is akin to yoga insofar as there is the withdrawal of the mind from sense objects, but he does not advocate more than that and he does not put forward the view that we find in classical Yoga about the necessity of total thought suppression.

It is always available but only if we choose to look for it. Patanjali says that when the common linear thinking ends and disbands, the meditation starts to bear its fruitful results; and conclusion of the meditation might as well be Samadhi (complete incorporation).

According to Patanjali, insight as well as the intellect (buddhi) comes from a native source-less wisdom of the universal infinite mind and that is the ever available clear light inhabiting behind the awareness also called as the param purusha. When the Sattvic ego only remains during deep meditation, is called Asmita Samadhi.

His yoga is one part spirituality and one part physical fitness, paving the way toward a united mind and body. As long as we remain dependent on external stimulus and our senses remain scattered rather than bound, our yoga practice shall remain externally oriented within the first four limbs: yama, niyama, asana and pranayama.
