Our body mind complex is made up of three gunas, and ahaMkAra is part of body mind complex.  As a result, we can’t escape the three gunas and we are forced to live with the three gunas and saguna ahaMkAra.  To handle the ahaMkAra, we must understand ahaMkAra and which guna is dominant in us and how the three gunas behave.  We must understand how the three gunas impact our material life and spiritual life. 

Definition:

• Satvic guna is a personality inclined to learn more and more; predisposed to acquire more knowledge.
• Rajo guna is a personality that tends to act more; tends to do more; and wants to use karmēndriya more than JñAnendriya;
• Tamo guna is a personality always in doubt, not sure what to do; in eternal conflict, delusion and procrastination.

How each guna bind:

• Satvic mind has a knowing tendency and naturally addicted to introspect, which is conducive to learning.
• Rajasic mind always wants to do something or other.  And for that it needs infrastructure and karmēndriya.  Rajasic mind is addicted to karma
• Tāmo guna mind is not sure about what infrastructure it needs.  It is attached to negligence and carelessness.

Verse 10

Sattva manifests by overpowering rajas and tamas.  Rajas (manifests by overpowering) sattva and tamas.  Tamas (manifests by overpowering) sattva and rajas, Oh Arjuna!

Everything in creation is a product of prakriti and therefore everything has all three gunas, but the proportion is not uniform.  Before creation, the three gunas were in equal proportion.  After the creation, the distribution of the three gunas is disturbed and they are not in the equal proportion.  Tāmo guna will be dominant in an inert object.  Plant has a little bit more of sattva and rājo guna, but it doesn’t have the capacity to learn and has a limited capacity of action like growing.  Animals have more dominant rājo and sattva guna than plants.  Humans have more rājo guna and sattva guan than animals.   All human beings do not have the same proportion of gunas; some of them have more sattva guna, some of them have more rājo guna and some have more tāmo guna.

For satvic person, satvic guna is dominant overpowering, rājo guna and tāmo guna.  For a rajasic person, rājo guna is dominant overpowering sattva guna and tāmo guna.  For a tamasic person tāmo guna is dominant, overpowering sattva guna and rājo guna. 

However, a person’s dominant guna (personality) can be transformed, but the rate of transformation may be different from person to person.  All sadhanas in scriptures are meant for transforming gunas.  Most people are born as tāmo guna predominant person (e.g. babies sleep more).  Life has to start with  karma and that is why scriptures prescribe karma yoga before jñāna yoga.

Rājo guna is of two types: 

1. RTS:  Rājo guna backed by Tāmo guna and followed by sattva guna.  Such a person will be selfish for the fulfilment of his own desires.  Scriptures say start with selfish activities.
2. RST:  Once selfishly active, convert this order to Rājo guna, followed by sattva guna and then followed by Tāmo guna. For this person, actions are selfless actions.  The activities are beneficial to more people, not just for himself. 

When the mind has become a mature mind, then convert the rajasic tendencies to satvic tendencies.  Convert to a sattva guna dominant mind, followed by rājo guna and then followed by Tamo guna.  RTS to RST to SRT.  Inactivity to selfish activity to selfless activities to inquiry is our journey.  When a person comes to the stage of inquiry, that person has already contributed to society through karma yoga and he should not have any feeling of guilt. 

Progress from Guna Sudhra (less active) to guna vaishya (Selfishly active) to guna kShatriya  (Selflessly active) to Guna brAhmaNa  (Pursuit of knowledge.

Verse 11:

When the light of knowledge grows in all the sense organs in this body, then, one should know that sattva is predominant.

Lord Krishna is now entering the third topic, that is lingam:  Indication or characteristics of gunas.   How do we know which guna is dominant in us?

The five sense organs provide knowledge of external world.  In a sattva guna dominant person, these five sense organs are bright, alert and have a great absorbing capacity. 

Verse 12

Greed, activity, commencement of works, restlessness, and craving – these appear when rajas is predominant, Oh Arjuna!

When rājo guna is dominant, that person will always be active and not have time for inquiry.  They will initiate many activities and projects  Their mind is ever restless and impatient.  They also expect the same amount of speed from the people around them.  Rajasic activities are very important for materialistic growth of a country. 

Verse 13

Dullness, inaction, negligence and delusion – these appear when tamas is predominant, Oh Arjuna!

In a tamasic person, all the sense organs are dull.  He is neither contemplative nor active.  Both sattva guna and rājo guna are dominated by tāmo guna.  He is negligent and careless.  Does not know what he wants to do.  Neither he can decide, nor will he take others advice. 

Based on these lingam or indicators, we should infer the predominant guna in ourselves.  Use this inference to gradually improve our character and gunas.
