इन्द्रियाणि पराण्याहुरिन्द्रियेभ्यः परं मनः।
मनसस्तु परा बुद्धिर्यो बुद्धेः परतस्तु सः।।3.42।।
3.42 They say that the organs are superior (to the gross body); the mind is superior to the organs; but the intellect is superior to the mind. However, the one who is superior to the intellect is He.
3.42 The senses are called the important obstacles of knowledge, because when the senses keep operating on their objects, the knowledge of the self cannot arise. The mind is higher than the senses: even if the senses are withdrawn, if the Manas (mind) ruminates over sense objects, knowledge of the self cannot be had. The intellect (Buddhi) is greater than the mind, i.e., even if the mind is indifferent to sense objects, a perverted decision by the intellect can obstruct the dawn of the knowledge of the self. But even if all of them upto the intellect are ietened from their activity, still when desire, identified with will, originating from Rajas, is operating, it by itself obstructs the knowledge of the self by inducing the senses etc., to operate in their fields. Thus it is said here: But what is greater than intellect is that. What is greater than the intellect - is desire. Such is the sense of the last sentence here.
