Japjee pauRee 7th

Jae Jug chaarae aarjaa jor dasooNee hoe||
One might live the four ages through ten times,
Navaa khanDaa vich jaaNeeai naal chalai sabh koe||
Become known through all of the nine continents,
Cha(n)gaa naaou rakhaae kai jas keerat jag lae-e||
Become the ruler of all living beings, with all in subservience to one. May have prestige, fame and fortune.
Jae tis nadar na aavaee ta vat na puchai kae||
Yet, who can be found to truly care for one, if that one does not, first, earn Gods Grace
Keetaa a(n)dar keeT kar dosee dos dharae||
That one will be slandered, cheated, disrespected as though having the insignificance of a worm, and will be condemned as a sinner, by the even the most sinful one.
Naanak nirguN guN karae guN va(n)tiaa guN dae||
In this pauRee Guru Naanak speaks of the mortal condition.
Taehaa koe na sujhaee je tis guN koe karae ||7||
His message is that no one can become virtuous by ones own efforts.

Pyareeoo, think of the sants that are slandered, those responsible for the conversion of thousands, yet others still will point fingers, and pick that one apart. Those public figures, in prestigious places of power, how many enemies, will ferret out every fault?

God is the bestower of virtues. Realization of Waheguru gives even the unworthiest one value, and enlightens the worshipper.
No mortal can stand before GOD and show any worth.
Nothing counts, in the end when, one stands before Dharm Raj, except the Grace of Waheguru.
By His Grace, we are given precious human life, a chance to put forth efforts.
By His Grace, we are granted the divine gift of His Naam.
By His Grace, we are united in realization with Him.
No one can become virtuous by ones own efforts, how ever long one lives, even if ones lifespan, is multiplied by the four ages (juga), ten times.
A clarification...
In Kal Jug mortal life span is roughly a hundred years, give or take twenty five, more or less.
In the preceding age, Duapur, the mortal life span was ten times longer.
Biblical history, going back only 6 thousand years, has recorded from 800 years to 1200 years as the mortal life span, before the great flood. Let us round this to a thousand years
In the preceding age Traita, the mortal life span was again ten times longer, amounting to roughly ten thousand years..
And finally in the age preceding of SatJug, mortal lifespan was approximately one hundred thousand years.

Sat Jug - the lifespan of the mortal was100,000 yrs.
Traita - the life span of mortal was 10,000 yrs
Duapur - the lifespan of mortal was 1,000yrs
Kaljug - the life span of mortal is 100yrs
(ages are rounded to 100 for convenience sake)
The life span of mortal man decreases ten times in suceeding Jug.

Of course in the final analysis, the principal purpose is to show, however long mortal lives, one can never have virtue with out God's GRACE
Sorry that I have not explained this before, I am not a scholar, and have my facts as they come, Given the proper names for those ages, I remember them simply, as:
Golden age (Satyug) 4 legs of spirituality
Silver age (Traita) 3 legs of spirituality
Bronze age (Duapar) 2 legs of spirituality
Iron age (Kal jug) 1 leg of spirituality

(panna 880 Siri Guru Granth Sahib Ji)
Perhaps because as a child being taught biblical history, there was such an example.
King Nebucanezzer of Babylon had a dream of a statue having a golden head, silver torso, bronze legs, and feet or iron and clay.

There was a Hebrew lad by name of Daniel, whom he had put into a den of lions, but who remained unharmed. Impressed by this, the king called Daniel for an interpretation of his dream, Daniel explained the statue represented four eras corresponding to Empires, and succeeding rule. At that time Babylon ruled the (their) entire known world. It’s kingdom would give way to lesser rulers and so on, until finally, the world would be broken into many small kingdoms, (like present) and would topple from it's weakness (the mixture of iron and clay)
In a simple way paralleling the teaching, in that, of only one leg left of spiritual life.
So, in my mind I have always related the image of that statue, to the 4 ages, as described by Vedic teachings, and referred to in Siri Guru Granth Sahib as Kal Jug
The proper names of the 4 ages...
