5.3 jñēyaḥ should be known, saḥ he, nityasaṅnyāsī perpetual ascetic, yaḥ who, na not, dvēṣṭi hates, na not, kāṅkṣati desires, nirdvandvaḥ one free from the pairs of opposites, hi verily, mahābāhō O mighty-armed, sukham easily, bandhāt from bondage, pramucyatē is set free.
Commentary:
A man does not become a Sannyasi by merely giving up actions because of laziness or ignorance or some family arrel or calamity or unemployment. A true Sannyasi is not a hypocritical coward.The Karma Yogi who neither hates pain and the objects which give him pain, nor desires pleasure and the objects that give him pleasure, who has neither attachment nor aversion to any sense-object and who has risen above the pairs of heat and cold, joy and sorrow, success and failure, victory and defeat, gain and loss, praise and censure, honour and dishonour, should be known as a perpetual Sannyasi though he is ever engaged in action.One need not have taken Sannyasa formally but if he has the above mental attitutde, he is a perpetual Sannyasi. Mere ochre-coloured robe cannot make one a Sannyasi. What is wanted is a pure heart with true renunciation of egoism and desires. Physical renunciation of objects is no renunciation at all. (Cf.VI.1)
