Non-Violence, truth, non-stealing, continence (being absorbed in a pure state of a consciousness) forgiveness, endurance, compassion, humility, moderate diet and cleanliness are the TEN RULE of of CONDUCT (yama). Penance (austerity), contentment, belief (faith) in the Supreme (God), charity, worship of God, listening to the recitations of sacred scriptures, modesty, a discerning intellect, japa (Mantra Repetition) and sacrifice are the TEN OBSERVANCE (Niyama).
Dwelling in the hermitage, being devold of all thoughts (excess mentatioin), yoga should be practiced in the way instructed by the Guru. Overheating, exertion, talkativeness, adhearing of rules, being in the company of the common people are unsteadiness ( wavering mind ) are the SIX (CAUSES)which destroy yoga.
