Chapter 14
Proclivities to Know 
This diagnostic chapter of 27 slokas, known as gunatraya vibhãga yoga, Differentiation of Qualities Three, details the three human proclivities - virtue, passion and delusion. It concludes with the identification of the realized spirit.
However, it may be noted that s3, s4 and s19 that deal with the Nature and the Spirit are digressions, and thus are interpolations. 
1 
 Thus spoke the Lord:
 Pass I now thee that knowledge
 With which sages free themselves.
2  
 Knows whoso this reaches Me 
 Keeps thus births ’n deaths at bay.
5  
 To tie the Spirit ’n body tight
 Uses Nature as its threads 
 Virtue, passion as well delusion.  
6
 Spirit as well gets well enticed
 By the charms of life well-led  
 Steeped in wisdom and virtue.  
7  
 Frames of passion as it weds
 Spirit gets fond of joys of life.  
8  
 It’s in delusion Spirit with sloth  
 Doth go in tow on wrong path.   
9  
 Gives man virtue life of ease
 Grinds him passion in despair
 Deprives delusion him of reason.
10 
 Of the trio often 
 Takes as lead role one of these
 Others to sidelines are confined.
11  
 Wearing wisdom on his sleeve
 Radiates virtuous throughout life. 
12 
 Plain greedy, or ever restive
 It’s the way all passionate live.    
13    
 Dull in mind
 And perverted
 In work lethargic
 He’s but deluded.
14  
 Peaks as virtue dies as one
 Ascends he the State Highest.
15 
 Dies if one with passion on hold
 Comes he back to resume things, 
 Lives who deluded all his life
 Gets he none better in rebirths. 
16  
 Virtuous sully never their lives 
Rue passionate as chase joys  
 Go down deluded drain of life.
17  
 Gives as virtue wisdom true  
 Renders passion unto grief 
 Leads as delusion into sloth. 
18  
 Echelons virtuous reach higher  
 Remain ‘as is where’ passionate
 Go down ladder ever the deluded.
20  
 Out of orbit if thou go 
 Of Nature that grips thy mind
 Freed be thou of recurring births. 
21  
 Thus spoke Arjuna:
 Can man ever, rein in matter,
 Is there regimen that reins it?
22  
 Thus spoke the Lord:
 With no let or ever hindrance  
 Whatever it be he lets go, 
 Takes he things all as they come
 With none fondness or distaste.
23  
 Seeing it all nature's work 
 From the fringes of conscience
 Detached he watches goings on.  
24  
 It’s in fairness that he weighs
 Affairs of life in fine balance.
25  
 Sans self, ego, self-realized 
 Works his way to state tranquil.
26  
 It’s by capping his nature  
 Wavers he not from the path 
 That which truly leads to Me
 And in end he turns Brahman.
27  
 It’s Me Immortal self of Brahman  
 Dharma eternal that’s All-Blissful.
