Time can be split into 3 parts: used (past), coming (future), and right now (present). In Persian the past is known as Mazi, future is known as Mustkbl and present is known as Haal. In Sanskrit they are Bhoot, Bhvish and Vartmaan.

The past is the steps you have taken. The breath which has left you. The river that has flown. By keeping the lessons of Mazi in mind, the wise clear their Mustkbl, but the truth is that we only have control over Haal. We only have Haal.

Bhoot is the used breaths, Bhvish the coming breaths, and Vartmaan is the breath we hold in our mouth right now. The breath in our mouths will make our Bhvish. Those that spruce the breath they hold in their mouth, their Bhoot is improved and their Bhvish will be illuminated and open. Often people will spend their Vartmaan in the memories of their Mazi, or in the worries or apprehension of their Mustkbl. They are so engrossed in the the memories of Mazi or the worries of Mustkbl that they forget their Haal.

In the womb of Vartmaan, Mazi is born. The foundations for your castles of Bhvish, are laid by your Vartmaan, but we do not care for our Vartmaan.

Bhai Vir Singh Ji says - The memories of Mazi are eating away at my bones and worries of Mustkbl are burning them away.

ਬੀਤ ਗਈ ਦੀ ਯਾਦ ਪਈ ਹੱਡਾਂ ਨੂੰ ਖਾਵੇ।
ਆਉਣ ਵਾਲੇ ਦਾ ਸਹਿਮ ਪਿਆ ਮਨ ਨੂੰ ਤੜਫਾਵੇ।

When man is old and looks towards their Bhvish they see only Death, and so they glance towards their Bhoot and live in their memories. As death is far, the young burn in the fears of tomorrow. Man only has Vartmaan in their hands. Those that waste their Vartmaan in memories of their Bhoot and those that burn their Vartmaan in fear of their Bhvish are fools. The wise spend today improving their Vartmaan and do not waste their today in memories of yesterday or the fears of tomorrow.

A Gursikh uses their Today.
