How many of you have sometimes closed your eyes & tried to be peaceful?
Now what is the link between the above two questions? When you see your body in the mirror, you are seeing & relating yourself to this body of flesh & bones. When you try to close your eyes & try to be peaceful, you are trying not to link yourself to this body but to something inward inside you where you can find peace. What is that inward thing that you are trying to find where you find yourself to be more peaceful? Yes, It's your Soul. In Soul, there is peace & you are trying to delve into that only in times of closing your eyes or in meditation.
I am remembering an old English song whose two lines are here;
"Faces.......all around different faces I see,
Some are happy, some in misery.............."
On this earth there are more than 7 billion people & each one is having a unique face. In fact God has created a vast variety of human bodies (to create illusion) & it seems that these all people are different only. But if we see closely then we shall find that all the bodies are made of similar nature elements & at Soul level all these are same only. Variety of bodies is external only but on deep analysis it is not so & are the same consequence of few nature elements. As per Bhagwat Gita, at soul level all these people are one only as one all pervasive soul pervades through all these bodies.
"Sri Krishna said:
There is nothing else besides Me,
Like clusters of Yarn-Beeds,
Formed by knots on a thread,
All this world is threaded on Me (universal soul)." (Bhagwat Gita: Chapter Seven verse 7)
So a person should not consider himself/herself limited to this body of flesh & bones but should consider himself/herself to be that universal soul only.
In fact a person's soul is infinite, omnipresent and is diffused everywhere throughout the space. A person's soul is as much same in London or New York as in Bombay, although it can only apprehend and feel and act where the body is. As the soul is subtle so it is not the object of physical perception.
Human body is made of Eight constituents of material nature. These elements are Earth, water, fire, air, ether, mind, intelligence and false ego. At death when the body perishes it is dissolved in these elements only but the soul which is indestructible survives. So it's up to you, if you perceive yourself to be a body then one day you shall die but if you consider yourself to be indestructible, infinite, omnipresent universal soul, then there is no death for you & you are immortal.
Here below is a saying from Upanishad which explains about the mortal body & immortal soul:
"It is true that the body is mortal, that it is under the power of death,but it is also the dwelling place of Atman (Soul), the Spirit of immortal life..............when a man is in the joy of the Spirit, he is free from all bondage, the bondage of pleasure and pain."
Same is said in Bhagwat Gita:
"na jayate mriyate va kadacin
nayam bhutva bhavita va na bhuyah
ajo nityah sasvato ’yam purano
na hanyate hanyamane sarire" (Bhagwat Gita: Chapter Two verse 20)
"Sri Krishna said: O Arjuna, The soul is never born nor dies at any time. Soul has not come into being, does not come into being, and will not come into being. Soul is unborn, eternal, ever-existing and primeval. Soul is not slain when the body is slain."
