What earth is beneath my feet is over the bodies of my dead ones. I have personally seen several stalwarts being buried beneath the earth. Since the normal span of human life is two days, (that of yesterday and morrow or of birth and death respectively), you had better get quickly on the path leading to Allah. This is what Latif advises.
Hazrat Ali recommended to remember death frequently; to work well for the world, as if you were going to live for a thousand years, and to hasten to do good for the Hereafter, as if you were going to die tomorrow. (Nahj-ul-Balagha).
Note: The Arab Philosopher Abual Alai Maghri had contained the life span into three days, to wit, Yesterday or the past, today or the present, and tomorrow or the future. But he should have realized that what we call the present is so fleeting that as soon as we hardly take stock of it, it is already changed into the past. I think Shah has done better by containing the life span into two days only - the yesterday and the morrow.
Moulana Azad in his غبار خاطر has gone a step further and measured the normal span of human life by the foot scale. According to him the distance between the two eternities is merely a cubit, which could be traversed in a minute or a fraction of a minute.
بدنامی حیات دو روز نبود بیش
واں ہم کلیم! با توچہ گویم چناں گذشت
یک روز صرف بستنِ دل شد باین وآن
روزِ دگر بکندن دل زین و آں گذشت
(Kalim)
This infamous life did not last for more than two days. That too, O Kalim! it is difficult to say how they passed. The first day was passed in creating associations here and there, and the second day was passed in uprooting them.

The earth under my feet, is above many loved ones,
Many brave and strong ones are covered with dust,
life lasts for few, get up and seek.

The earth under my feet is over many of my dear ones,
We saw many braves overlaid with dust,
Life lasts only a few days, get up and seek right path.
