Alexander lived just for 33 years but he created one of the biggest empires ever on earth. He had lots of wealth which included, Gold, Pearls, Diamonds etc. in abundance. But at his death he asked his advisers and officers to keep both of his hands open during his funnel procession. Why he asked his people to do so? Actually Alexander Just wanted to tell and teach others that in this world every one comes with empty hands and goes also empty handed. Alexander the Great might have conquered many kingdoms but while leaving this world nothing was with him, every thing was left behind. So he taught to the world that when every thing has to be left here only then why to give troubles to others, why to gather so much wealth & all these worldly comforts.
As per Bhagwat Gita, whatever belongs to you today, belonged to someone else earlier and shall belong to some one else in future. Change is the law of the universe. We have not brought anything at the time of birth. Everyone came in this world empty handed and shall go the same way. Everything belongs to God only. We are mistakenly enjoying the thought that this is ours. It is this false happiness that is the cause of our sorrows.
On this earth no one is immortal & has ever stayed permanently on this earth. Our Life is not permanent on this earth & it is for a limited period of time after which it shall pass away. So we all should know the real purpose of life & should not let God slip out of our mind & life anytime, as He only shall save us during this life & also after this life.
"jatasya hi dhruvo mrityur
dhruvam janma mrtasya cha
tasmad apariharye ’rthe
na tvam socitum arhasi" (Bhagwat Gita: Chapter Two verse 27)
"Sri Krishna said: O Arjuna: One who has taken his birth is sure to die, and after death one is sure to take birth again. Therefore, in the unavoidable discharge of your duty, you should not lament."
So knowing the truth about life & death, we should worship the God at all times. Lord Krishna promises in Bhagwat Gita that he shall protect His devotees in this life & in after life also. So let’s all be devotees of Lord Krishna.
