Chapter 12
Doctrine of Faith  
This chapter of 20 slokas, known as bhakti yoga, Doctrine of Faith, enumerates the human qualities that are endearing to the Supreme Spirit. In this also are discussed the ways in which one still could win the Lord’s favour yet failing to set store on Him. 
1  
 Thus spoke Arjuna:
 Pray tell who’s better realized, 
 One that devoted as stated 
 Or relies who on God Obscure.
2  
 Thus spoke the Lord:
 Me in devotion who worships   
 Him I reckon as well realized.
 
 3
 Having said that add I might
 Looks as one to God Obscure -
 
 4  
 Doth he fine with senses reined  
 If well disposed towards the world.
 
 5  
 But it’s tough ask nonetheless  
 For one to realize God Obscure.
6  
 Whosoever hath faith in Me
 And leans on Me heart ’n soul -   
7  
 Him I help to cross over 
 Ocean vast of births ’n deaths.
8  
 If thou develop faith in Me  
 Take for granted I take thee.
9  
 Were thee to fail develop faith
 It’s not thou reached blind alley, 
 Ever Me having in thy mind
 Practice lets thee turn the bend.
10  
 If thou feel that’s hard as well 
 Indulge then in deeds Me please.
11  
 If thou find that difficult too 
 Give thyself to Me Supreme 
 Act then with thy subdued mind   
 With no thought for what follows. 
 
 12  
 Scores thought over mere roting 
 Betters meditation awareness too 
 What helps man to find moorings
 Are acts his with no axe to grind.
13 
 Kind-hearted ’n considerate
 Friendly natured, forgiving too 
 Lays no store on highs and lows
 Suffers no pride ’n possessive not –
14  
 Who's patient ’n cheerful  
 Self-willed as well persevering,
 Who's hearty ever at work  
 Makes he devout My beloved.
 
 15 
 Troubles he none or perturbs 
 It’s such poised I’m proud of.
16 
 Who’s simple, never in want  
 Covets he not in vantage post
 Shakes him none, he keeps his nerve
 It’s such who Me please the most.
 
 17  
 He’s My darling who craves not
 Yet won’t shun the pleasures of life
 Takes but things all as they come.
18  
 Treats he equal friends ’n foes  
 Scorn or honour minds he not
 Keeps he cool in grief and joy  
 Nurses for none soft centre –
19  
 Pats ’n slights all in the score
 Treats as equal score My man 
 Takes he in his stride his lot  
 But won’t put the blame on Me.
 
 20  
 Who in dharma this engage
 Them I hold in special esteem.
Ends thus:
 Doctrine of Faith,
 The Twelfth Chapter 
 Of Bhagavad-Gita,
 Treatise of self-help.
Note that this fillip is to overcome the the ssytemic 500 words uploading hurdle.
Though it is a matter of consensus that Bhagvad-Gita in the present length of seven hundred slokas has many an interpolation to it, but no meaningful attempt has ever been made to delve into the nature and extent, not to speak of the effect of these on the Hindu society at large. 
The methodical codification of interpolations carried out here, for the first time ever, puts the true character of Gita in proper perspective. Identified here are hundred and ten slokas of deviant nature and or of partisan character, the source of so much misunderstanding about Bhagvad-Gita, the book extraordinary, in certain sections of the Hindu fold. 
In the long run, exposing and expunging these mischievous insertions is bound to bring in new readers from these quarters to this over two millennia old classic besides altering the misconceptions of the existing adherents.
