Soul is eternal, omnipresent, immovable, everlasting, unmanifested, unthinkable and immutable.

Sankhya Yoga

Chapter 2, Verse 25

 

avyakto’yam acintyo’yam 

avikāryo’yam ucyate 

tasmād evaṁ viditvainaṁ 

nānuśocitum arhasi

 

It is unmanifest, it is unthinkable, it is immutable, so is it described;  

therefore, knowing it as such, you should not grieve.

 

Here Krishna asks Arjuna, “Why are you grieving, My dear? Why are you crying? The soul ‘is unmanifest, it is unthinkable’”. The soul can’t be conceived by the mind, the mind can’t comprehend it. The mind can’t understand the soul, because the soul  

is beyond the mind.

 

If you are looking at the soul only from the point of view of the mind, do you think that the mind can understand the soul? A mind which is always moving around is, ‘cañcala’, “restless,” dancing and jumping like a monkey, from one thought to the other. How can the mind, which is in constant movement, be still and perceive the unmovable? The mind will always move from one thing to another until one has gone deeply into the sadhana, deeply into meditation and calmed the mind. Only then will the soul reveal itself. But before that, if the mind is still jumping around, the soul is unknowable.

 

Krishna says that the soul “is immutable.” Everything which is mutable is bound by the mind, and whatever is from the mind is bound by Maya Prakriti, bound by the laws of Nature. The soul is completely separate from Prakriti. It undergoes no transformation, in any circumstance. When one realises the soul itself, one knows that it is eternal, omnipresent, immovable, everlasting, unmanifested, unthinkable and immutable. So, Krishna asks, “Arjuna, why are you grieving?”
