Chapter 17
Science of Devotion 
This chapter of 28 slokas, known as sraddhã traya vibhãga yoga, Threefold Devotion, deals with the spiritual and temporal aptitudes of man. S11-s13 that deal with the virtuous, the passionate and the deluded in ritualistic sense and s 23 -28 concerning Om, Tat, Sat and Asat of the Vedic hymns are clear interpolations for reasons the reader is familiar with. 
However, s7 –
s10 that deal with the food habits of the virtuous, the passionate and the deluded would pose a problem in determining whether or not they are interpolations. Can eating habits be linked to the innate nature of man in an infallible manner? Perhaps, some future research and analysis might resolve the universality or otherwise of this averment, and till then, it is appropriate to reserve the judgment on these. 
1 
 Thus spoke Arjuna:
 None the regard for scriptures 
 Who tend to manage life their well
 What Thou say of such of beings
 Virtuous, passionate or merely deluded.
2  
 Thus spoke the Lord:
 It’s one’s nature that tends him
 To be virtuous, passionate, or deluded.
3  
 Beings all have faith in some 
 It's one's nature that shapes it.
4  
 Virtuous seek gods in worship  
 Opt passionate to humour ghosts      
 Turn all deluded towards the Hades.
5  
 Hoping for there all to gain
 Indulge vain in austerities
 Though not endorsed by scriptures. 
6  
 It’s in delusion they all fast
 Emaciating frames of theirs, 
 Thus in foolishness they all  
 Famish Mine own Self in them. 
7 
 As with habits so with palates 
 Come to tend all in three ways.
8 
 Opt virtuous all recipes fine
 Sustain health ’n enhance strength.
9  
 Hot ’n spicy, and pungent, 
 Prefer food passionate that ill-suits.
10  
 Food of deluded is all stale 
 Long in storage, and impure.  
15  
 Rings with truth ’n laced with warmth
 It's speech austere that’s well-meaning. 
16 
 Simple ’n stoic
 Kind and candid
 It’s mind austere  
 With self-control.
17  
 Wanting none
 Never in turn,
 Done in concern
 Deed it’s austere. 
18  
 It’s in pretension passionate live
 Eye they have on name ’n fame.
19  
 With troubled mind all deluded live
 Hurt themselves ’n others as well.
20  
 Virtuous deed is that extends
 Helping hand to one in need
 Guided by the zeal to serve.    
21  
 Deed passionate is quid pro quo
 Ever done with some end in mind.  
22 
 Aiding dubious with disdain 
 It’s deed deluded that lacks goal.
Ends thus:
 Science of Devotion,
 The Seventeenth Chapter   
 Of Bhagavad-Gita,
 Treatise of self-help.
It may be noted that this tailpiece is meant to facilitate its seamless publication with the rest of the text
Bhagavad-Gita is the most beautiful, perhaps the only true philosophical song existing in any known tongue’ – so opined William von Humboldt, who wrote seven-hundred verses in its praise.  
All the same, the boon of an oral tradition that kept it alive for over two millennia became its bane with the proliferation of interpolations therein. Besides muddying its pristine philosophy, these insertions affect the sequential conformity and structural economy of the grand discourse. What is worse, to the chagrin of the majority of the Hindus, some of these legitimize the inimical caste system while upholding the priestly perks and prejudices.
This rendition seeks to restore to the Gita, its original character by ridding it of hundred and ten interpolations, which tend to keep the skeptics away from it. And ironically these muddle the understanding of the adherents as well.
