इदं ते नातपस्काय नाभक्ताय कदाचन।
न चाशुश्रूषवे वाच्यं न च मां योऽभ्यसूयति।।18.67।।
18.67. This [knowledge] is for you, and it should never be imparted to one who does not observe austerities; to him who has no devotion; to him who has no desire to listen; and to him who is indignant towards Me.
18.67 Idam etc. If the secrecy of this knowledge is maintained it would yield success, because It is out of reach of all [ordinary] persons. When the knot of sin is cut off through observing austerities, then only the results of good act is ready to become ripe. Hence, austerity comes first. Due to austerity, faith is born. The same (faith) is devotion here. The faith, even if it is born, does not grow well, in case it becomes visible only for a moment and then perishes like lightning. Therefore to help its growth, the desire to listen to is [next]. In the case of certain person, even all this arises with regard to the useless knowledge of the dry Sankhya (reasoning) system that admits no Supreme Lord. Even with regard to a system that adimts the Supreme Lord, it may, n the case of another person-on account of his craving for fruit of action-emerge by raising the fruit-of-action alone to the status of importance and by humbling down ones own Worshipful Self to the role of an instrument in achieving that fruit It has been declared : The agent also [is an auxiliary], because he is for the action [enjoined]. (JS, III, i, 6); and Actions also [are auxiliary] because they are for the purpose of fruits. (JS, III, i, 4). Thus in both the instances there is indignation, meaning disregard with the Bhagavat (Self) - This is the purport.
Idam te naatapaskaaya naabhaktaaya kadaachana; Na chaashushrooshave vaachyam na cha maam yo’bhyasooyati.
idam—this; te—by you; na—never; atapaskāya—to those who are not austere; na—never; abhaktāya—to those who are not devoted; kadāchana—at any time; na—never; cha—also; aśhuśhrūṣhave—to those who are averse to listening (to spiritual topics); vāchyam—to be spoken; na—never; cha—also; mām—toward me; yaḥ—who; abhyasūyati—those who are envious
