In Bhagavad Gita, Chapter 15, Verses 16 and 17, the speaker delivers one of the most definitive cosmological statements in all of scripture. He clearly categorizes all existence into three distinct Supreme Entities (Purushas), drawing a sharp line between the perishable ruler of this world, the imperishable ruler of the intermediate realm, and the absolute Supreme God who sustains everything.
These two verses form the core logic of Chapter 15 (Purushottama Yoga), providing the master key to understanding the Vedic hierarchy.
द्वाविमौ पुरुषौ लोके क्षरश्चाक्षर एव च । क्षरः सर्वाणि भूतानि कूटस्थोऽक्षर उच्यते ॥ १६ ॥
उत्तमः पुरुषस्त्वन्यः परमात्मेत्युदाहृतः । यो लोकत्रयमाविश्य बिभर्त्यव्यय ईश्वरः ॥ १७ ॥
Verse 16 introduces two Gods, but Verse 17 immediately introduces a Third, Higher God who is completely distinct (Anyaḥ) from the first two:
[ 1. KSHAR PURUSH ] ──► Kaal Brahm ──► Perishable Ruler of 21 Universes
│
[ 2. AKSHAR PURUSH ] ──► Parabrahm ──► Imperishable Ruler of 7 Shankh Universes
│
[ 3. PARAM AKSHAR PURUSH ] ──► KavirDev (God Kabir) ──► Uttam Purush / Supreme Lord in Satlok
A very common mistake in mainstream commentary is grouping all existence into just two categories: the soul and God.
However, Gita 15.17 uses the explicit Sanskrit phrase "Uttamaḥ puruṣas tv anyaḥ"—meaning "The Supreme Person is DIFFERENT from these two."
| Entity | Category | Nature / Realm | Primary Function |
|---|---|---|---|
| Kaal Brahm | Kshar Purush (Gita 15.16) | Perishable / 21 Universes | Binds souls via Karma & Time |
| Parabrahm | Akshar Purush (Gita 15.16) | Imperishable / 7 Shankh Universes | Intermediate Administration |
| KavirDev (Kabir) | Uttam Purush / Paramatma (Gita 15.17) | Eternal / Satlok | Sustains all worlds & grants Moksha |
The Uttam Purush (Supreme Person) is Param Akshar Brahm (KavirDev / Supreme God Kabir). He is distinct from both Kshar Purush (Kaal) and Akshar Purush (Parabrahm), and He resides in the unchangeable realm of Satlok.
Because the speaker of the Gita is Kaal Brahm (Kshar Purush). He acknowledges his own limitations and truthfully informs Arjuna that the ultimate Lord who preserves and sustains all three worlds is a separate, higher Supreme Being.
In Gita 8.20, the speaker mentions "Sanatan Unmanifest" which is beyond the lower unmanifest (Kaal). Gita 15.16–17 provides the exact names and categories for these levels, confirming that the Uttam Purush is the ultimate destination.
