It is stated in the Vedic literature that; labdhvā su-durlabham idaṁ bahu-sambhavānte (SB 11.9.29): "This body is achieved after many, many, many, many births, after millions and trillions of years." Because . . . you don't think that all of a sudden, by accident, we have got this body. There are other bodies—cats, dogs and so many bodies. Why in this civilized form of? There must have been some process. So this is said in the Vedic literature, labdhvā su-durlabham idaṁ bahu-sambhavānte, mānuṣyam artha-dam: "This human form of life is achieved after many, many millions of other forms of birth."
And what is this form? Mānuṣyam: human form, man. This mānuṣya is Sanskrit word, and English word, "man," there is similarity, Latin. Originally, this mānuṣyam, or "man" comes from the word Manu. Manu is the father of humankind. Mānuṣyam. So, why it is so rare? Artha-dam. You can attain the highest perfection, artha-dam. Artha means money, or artha means substance. Artha-dam.
So we are utilizing it for money-making. Artha means money also, but there is another meaning of artha. Artha means substance. We are missing the substance. We are attracted by material money only. So mānuṣyam artha-dam anityam apīha dhīraḥ. And anityam. Although artha-dam—it can deliver you the substance—but it is not permanent, anitya. Anitya means . . . nitya means eternal, permanent; anitya means just the opposite. So the scriptures, Vedic scripture, advises you mānuṣyam artha-dam apīha dhīraḥ.
But if you are dhīra—dhīra means sober, intelligent—then how you shall utilize it? Tūrṇaṁ yateta anu-mṛtyu na pated yāvat (SB 11.9.29). You should try to utilize your this human form of life to achieve the highest substance very soon. Tūrṇam means very soon. Why very soon? Now, anu-mṛtyu na pated yāvat. You do not know when your death will come. You do not know. So before death comes, just utilize yourself. Don't think that, "I am young man. Let me enjoy now. Eat, drink, be merry and enjoy." No. You should not neglect.
