The Unmanifest Soul – The Bhagavad Gita Chapter22 Verse25

अव्यक्तोऽयमचिन्त्योऽयमविकार्योऽयमुच्यते |
तस्मादेवं विदित्वैनं नानुशोचितुमर्हसि || 25||
Abyakto ayamachintyo ayama bikaaryo ayamuchyate
tasmaadebam viditwainam naanushochitumharshi
(Bhagavad Gita Chapter2 Verse25)

GENERAL MEANING:
This soul (inner, immortal self) is unmanifest, cannot be thought about, free from dualities and defects. Realizing this, the soul as such, you should be free from lamentations and agony.
