Thirukkural-On Wealth-On Wisdom-Kural-430

Add as a preferred source on Google

The wise have all blessings, even if not possessed with worldly goods,
But the ignorant rich have nothing.

The implication here, Rajaji would say, is that a discriminating mind is the greatest of all human assets. Without it, all other possessions will come to nothing.

A chronologically later parallel occurs in Pazhamozhi thus:
“Arivinaal maatchi onrillaa oruvan
Pridhinaal maanda thevanam
Mani ponnum, saanthamum maalaiyum inna
Aniyellaam aadaiyin pin" (Pazhamozhi )

A Biblical reference in the Proverbs is as under:

The wise shall inherit the earth, but shame
Shall be the promotion of fools
(Proverb: 3, 35)
