Bhagwad Gita - Post 190

Verse 17

But distinct is the Supreme Purusha called the highest Self, the indestructible Lord who, pervading the three worlds, sustains them.

Verse 18

As I transcend the perishable and am even higher than the imperishable, I am declared as the highest Purusha in the world and in the Vedas.

The Supreme Purusha is different from both the purusha and prakriti mentioned. He is called Paramatma, the Supreme Self. We may call the purusha of the Sankhya as a kind of self, but this is a Supreme Self which includes every other kind of self, and all selves are subsumed under this universal inclusiveness. 

In this verse (no. 18), the Supreme Lord Krishna confirms His position as Purushottama the Supreme Being of all existence by His validation of transcendence to both the kshara or perishable and akshara or imperishable.

The Brihadaranyaka Upanishad V.VI.I beginning manomayo-ayam puruso states: The resplendent Supreme Being is the ruler and lord of all governing all that exists.

Chinmaya explains in his own unique way, 

“If two trains are both moving at the same speed no movement is recognized by perceivers in both the trains. If the changes in the world of Matter --- the body, the mind and the intellect are recognized, then there must be a steady principle that illumines all these different changes. This constant factor among the Perishing is called the Imperishable.

This illumining factor gathers its status as the "Imperishable" only with reference to the "Perishable" realms. Once the perishable realms are transcended, the Imperishable amidst them Itself comes to shine forth as the Pure Infinite, which is the Purushottama. Since the Truth, Purushottama, is experienced only on transcending both the 'Perishable' and the 'Imperishable,' It is known by the term the 'Highest-Spirit' --- Purushottama. This term is used to indicate the Supreme-most Self, both by the ancient sacred volumes (Vedas), and by the poets and writers of the world.”

Bhagwad Gita - Post 189

Verse 16

Two Purushas there are in this world, the perishable and the imperishable. All beings are the perishable, and the Kutastha is called the imperishable.

There are two realities in this world, one being imperishable, the other being perishable. Which one is perishable, and which one is imperishable? 

All visible objects, including all jivas, are perishable. 

Yaddrsyam tannasyam is a brief sutra of Acharya Sankara:

Whatever is visible is perishable. This entire world is visible and, therefore, it has to be considered as Kshara, or perishable. This is cosmically true as well as individually true. 

But there is a Kutastha Atman inside us which transcends the five Koshas, beyond the physical, subtle and causal bodies there is a transcendental light shining within us; that is our real Self, that is the Atman, that is the Kutastha Chaitanya. It is the imperishable in us. 

Thus, there appears to be a twofold reality in this world, almost amounting to the peculiar relationship between the Purusha and the Prakriti of the Sankhya. 

For the Sankhya, there is nothing above Purusha and Prakriti. According to the Sankhya, there are only two realities—Consciousness on the one side and matter on the other side—and everything can be explained by the juxtaposition and the interaction of Purusha and Prakriti.

But, interestingly and very specially, the statement made here in this Bhagwad Gita verse is that there is a Being transcending this so-called Prakriti, and it is above even the Purusha. 

The perceiving consciousness and the perceived object are transcended in a universal consciousness that absorbs both into its original essence. 

It is here alone, in the Bhagawad Gita, that a transcendent opinion is held that there is an Absolute beyond the seeing or witnessing consciousness and the witnessed world. God is not simply consciousness; 

He is not simply an object of perception in the form of the whole universe. “Unthinkable Reality, Supreme Transcendence, Purushottama am I.”

Reader’s attention is drawn to the relevant exposition already covered under the theme “Creation of the Universe”, as under:-

“…….In the Gita, an entity / existence beyond Purusha and Prakriti is explained as PURUSHOTTAMA.

In the Gita, Purusha and Purushottama words are used frequently and one is used for the other term. Thus, if the existence of Purushottama is not properly grasped by the readers, then Purusha word used in the Gita may be interpreted as Purusha explained in the Sankhya.

In the Sankhya, Purusha and Prakriti, where Prakriti is not different from Purusha but only the primordial matter of the Purusha existing as spirit, are understood to be responsible for the creation.

If that be so, where were this Purusha and Prakriti (or the identity of Purusha as Spirit and Matter) before the creation took place?

Vedanta gives the answer, which aligns with the flow given above:

“Purusha (as described in the traditional Sankhya philosophy) and Prakriti are both latent in the Supreme. At the time of creation, they became operative”.

Thus, Bhagawad Gita conveys in a subtle manner that though one talks of Kshetra and Kshetrajna with respect to their  activated human body and for all such bodies, there is Kshetra and Kshetrajna, there is one Kshetrajna common to all, who is the Purushottama.

Bhagwad Gita - Post 188

Verse 14

Having become the fire Vaiśhvānara, I abide in the body of living beings and, associated with the Prana and Apana, digest the fourfold food.

Sri Krishna says that God exists inside all living beings as Vaiśhvānara, meaning “fire of digestion,” which is ignited by the power of God.  The Bṛihadāraṇyaka Upaniṣhad has also stated:

ayam agnir vaiśhvānaro yo ’yam antaḥ puruṣhe yenedam annaṁ achyate (5.9.1)

“God is the fire inside the stomach that enables living beings to digest food.”

It is a wonder that we are able to eat such a large variety of food, and yet derive enough energy to keep our bodies running throughout our lives, all due to the functioning of the Vaiśhvānara fire. 

It is supported by two vayus or forces known as the Praana and the Apaana vayus. 

The Praana vayu brings food towards the digestive organs. Vaiśhvānara is the process of digestion and metabolism. 

The Apaana vayu pushes non-essential portions of the food out into the world.

When the prana and the apana conjointly act at the root of the naval within the stomach, they operate in a different manner altogether, and go by the name of samana; and that creates a kind of heat in the stomach, which is necessary for the digestion of food. 

This heat is known as Vaiśhvānara-agni, the Universal Fire. It is the energy of God that operates through the metabolic process of individuals and causes the digestion of the four kinds of food—pachamyannam chaturvidham. 

Chaturvidham means four types and annam means food. Food is categorized into four types: 

1. Bhojya - Foods that are chewed, such as bread, chapatti, etc.  

2. Peya - These are mostly liquid or semi-solid foods which we have to swallow or drink, such as milk, juice, etc.  

3. Kośhya - Foods that are sucked, such as sugarcane.  

4. Lehya - This includes foods that are licked, such as honey, etc.

The expressions that He becomes the light of the sun, moon and fire etc. are meant to indicate the predicated relationship that these objects have in regard to Him. 

According to Ayurvedic sastra, we understand that there is a

fire in the stomach which digests all food sent there. When the fire is not blazing, there is no hunger, and when the fire is in order, we become hungry. 

Sometimes when the fire is not going nicely, treatment is required. In any case, this fire is representative of the Supreme Personality of Godhead. 

Vedic mantras also confirm that the Supreme Lord or Brahman is situated in the form of fire within the stomach and is digesting all kinds of foodstuff. Therefore since He is helping the digestion of all kinds of foodstuff, the living entity is not independent in the eating process.

Unless the Supreme Lord helps him in digesting, there is no possibility of eating. He thus produces and digests foodstuff, and, by His grace, we are enjoying life. 

In the 10th chapter Krishna has referred to the vibhūtis of the Supreme. He has explained how the Supreme, otherwise imperceptible and omnipresent, remains incomprehensible, though manifest in the whole creation. 

“What need is there for all this detailed knowledge, O Arjuna? Simply know that by one fraction of my being, I pervade and support this entire creation.”

(Chapter 10, verse 42)

In order to facilitate a full comprehension of the Supreme, Krishna lists a variety of objects and qualities. 

The references include letters, words, mountains, war-weapons, fame, patience, will, memory, spirituality and the rest. Finally he declares that all put together, the entire visible glory around us is merely one small fraction of the Supreme.

So we see that production, distribution and ultimate consumption of energy that happens in us, and happens in any other living being, is nothing but Easvara / Supreme Consciousness. 

Remembering the above essence is a great way to reduce our ego and see our oneness with the world. 

Love.
