Kadhalum Kadanthu Pogum Tamilyogi -
"காமம் கரஞ்சே கைக்கூடும் கார்மேல் வாரல் யார்க்கும்" (Kāmam karañcē kaikkūṭum Kārmēl vārāl yārkkum)
Or, in a more poetic translation:
"Love and War are equal, O Tamilyogi"
Which roughly translates to: "The heat of love is like the heat of war; both are equal." Kadhalum Kadanthu Pogum Tamilyogi
Here's the text in English:
A Tamil phrase!
"Love and conflict are indistinguishable, O seeker of Tamil knowledge" O seeker of Tamil knowledge"
