तिरुक्कुरळ् (सन्त तिरुवल्लुवर - तमिल वेद / उत्तरवेद: धर्म, अर्थ एवं काम सविस्तार हिन्दी भाषान्तर)

Wait! In line 120, standard is:
"செய்வார்க்கு" -> செய் - வார் - க்கு!
In line 118, standard is:

Wait! "ர்க்கு" and "தூக்கும்" - what do they have in common?
"க்"!
Wait! Could that glyph be "ர்" or "ர்க்" or "த்"?
Wait, why would "செய்வார்க்கு" have that glyph before 'கு'?
In "செய்வார்க்கு", before 'கு' is 'ர்க்' or 'ர்'!
Wait! In line 120, what is before 'கு'?
"செய்வா" + GLYPH + "கு"!
If standard is "செய்வார்க்கு", then GLYPH + "கு" = "ர்க்கு" or GLYPH is "ர்" (or "ரா")?
Wait, if GLYPH + "கு" = "வார்க்கு", what if the typesetter used a ligature or made an insane substitution?
Wait, what is that GLYPH?!
Let's look at the shape of that glyph in 118 and 120:

"வாணிகம் செய்வா [GLYPH] கு வாணிகம் பேணிப்"
Wait, look at GLYPH in line 120:
