==Discipline and Raja Yoga [Mental Discipline]==
[Rajayoga] insists first on a moral purification of the mentality. This preliminary is of supreme importance; without it the course of the rest of the Rajayoga is likely to be troubled, marred and full of unexpected mental, moral and physical perils. This moral purification is divided in the established system under two heads, five ''yamas''
and five ''niyamas''. The first are rules of moral self-control in conduct such as truth-speaking, abstinence from injury or killing, from theft etc.; but in reality these must be regarded as merely certain main indications of the general need of moral self-control and purity. ''Yama'' is, more largely, any self-discipline by which the rajasic egoism and its passions and desires in the human being are conquered and quieted into perfect cessation. The object is to create a moral calm, a void of the passions, and so prepare for the death of egoism in the rajasic human being. The ''niyamas''are equally a discipline of the mind by regular practices of which the highest is meditation on the divine Being, and their object is to create a sattwic calm, purity and preparation for concentration upon which the secure pursuance of the rest of the Yoga can be founded. <ref>http://incarnateword.in/cwsa/23/rajayoga#p9</ref>
It[Rajayoga]commences with the drawing both of the mind and senses from outward things...the real object of this mental discipline is to draw away the mind from the outward and the mental world into union with the divine Being. <ref>http://incarnateword.in/cwsa/23/rajayoga#p9</ref>
