Act of donating horse is high
Act of donating elephant is higher than that and yields more Punya
Act of donating land is higher than that
Act of donating Teel is higher than that
Act of donating Gold is higher than that
Act of donating food is higher than that. It is because not only humans but Pitars (dead ancestors) and Heavenly gods are satisfied by this act
The act of donating Kanya (Kanyadaan) is as equal as act of donating food.
The act of donating a cow is also as equal as act of donating food or act of donating Kanya ie Kanyadaan.
These are the words of God Himself.
But the higher act of giving or donation, above all these acts mentioned, is the act of donating Vidya (Skill, knowledge,Vidya)
The Punya earned by doing Varuthini Ekadashi is same as the Punya earned by act of donating Vidya (Skill, knowledge etc)
The Punya earned by donating a Kanya (Kanyadaan) with gold ornaments worn by her is so high that even Chitragupta cannot mention. By doing Vrat of Varuthini, equivalent Punya is attained.
