18.9 When rites like obligatory and occasional ceremonies and the great sacrifices enjoined on one's station and stage in life, are practised for their own sake, as worship of Myself and as a duty, relinishing possessiveness and fruits - such abandonment is regarded as Sattvika. It is noted in Sattva. The idea is that it is rooted in the knowledge of the meaning of the Sastras as it really is. That Sattva generates the knowledge of things as they really are, has been taught in:  'From Sattva arises knowledge' (14.17), and it will be further declared:  'That reason by which one knows action and renunciation, what ought to be done and what ought not to be done, fear and fearlessness, bondage and release, O Arjuna, is Sattvika' (18.30).
