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 one's 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.
