The doer who is free of attachment, who does not speak of himself as 'I', who is endowed with steadiness and zeal, steadiness being firmness, zeal being effort, and unmoved in the success or failure of the action being done, that is, undisturbed whether its fruit is gained or not, set going solely by the authority of scripture and not by longing for fruit and the rest; such a doer is called of sattva.
