If someone is not qualified for Karma Yoga, he can practice Karma Kanda:

1-10: Karma Yoga is better for you, as you are not qualified for Jnana Yoga. (Of course, Arjuna is a pure devotee and is qualified for more than Jnana Yoga, but in this context, when Krishna is giving instructions at progressive levels, the level He is referring to. If one is not qualified, then Jnana Yoga can create disruption in society, make one hypocritical, and make one’s livelihood difficult.)

10-16: If you are not qualified even for KY then practice KK

17-24: If you are qualified for JY, still practice KY to set example

25-29: KY-KK difference

30-35: How KY elevates

36-43: Overcome lust, the main obstacle on the path of KY

Bg 3.10

sahayajnah prajah srishtva

purovaca prajapatih

anena prasavishyadhvam

esha vo ‘stv ishtakamadhuk

SYNONYMS

saha — along with; yajnah — sacrifices; prajah — generations; srishtva — creating; pura — anciently; uvaca — said; prajapatih — the Lord of creatures; anena — by this; prasavishyadhvam — be more and more prosperous; eshah — this; vah — your; astu — let it be; ishta — of all desirable things; kamadhuk — bestower.

TRANSLATION

In the beginning of creation, the Lord of all creatures sent forth generations of men and demigods, along with sacrifices for Vishnu, and blessed them by saying, “Be thou happy by this yajna [sacrifice] because its performance will bestow upon you everything desirable for living happily and achieving liberation.”

We have discussed spiral progression.

So here we will discuss if one is not qualified for KY then one should practice KK.

saha-yajnah, with Yajnah,

prajah srishtva, Prajah (all living beings) created

puro, in ancient time. Vaca, said. Prajapatih, lord of all creatures

So different Acharyas refers Lord of creature as Vishnu or Brahma, SP has done a mix of both but the consequence is the same whoever we referred here.

So what does prajapatih says? anena prasavishyadhvam, so by this become prosperous become more and more prosperous.

esha vo ‘stv ishta-kama-dhuk, so let this be your ishta-kama-dhuk, Kama means desires, here Kama does not have a negative connotation. Kama means whatever your requirements, whatever your needs or necessities in life. So let this be your provider of ishta-kama-dhuk, whatever you desire it will provide.

So, what is this actually referring to?

Krishna is telling the system of Yajna has been present right from the beginning of creation. Just like when parents beget a child, they arrange for taking care of the child. Similarly, when the Lord creates living beings, He makes arrangements to take care of them. What is that arrangement? It is the system of Yajna. So, Yajna is esha vo ‘stv ishta-kama-dhuk – let this be the fulfiller of your desires. In these verses, Krishna talks about the system of cosmic cooperation between the devatas, the Supreme Lord, and human beings. This will be discussed a little later. Here, we will discuss that when the Lord creates, He doesn’t send living entities to the wilderness. We can see how the Lord arranges this through nature. For example, when a baby is born, food for the child is arranged in the womb, and milk is available through the mother. Every species in this world gets its food, and this is arranged by the Supreme Lord. In this way, the universe is perfectly complete, and the Lord has arranged to care for the needs of living beings.

Animals do not have any karmic result; they largely act on their instincts for the sake of eating, sleeping, mating, and defending. In human life, we have an advanced level of consciousness and the capacity to regulate eating, sleeping, mating, and defending. We also have the capacity to choose, so we can redirect our desires to choose spiritual pursuits. For human beings, Krishna provides the necessities of life, but we have the responsibility to discharge our material duties and spiritual duties

SP in purport: mentioned about purpose of creation and how Lord Vishnu is the ultimate goal.

The material creation by the Lord of creatures (Viṣṇu) is a chance offered to the conditioned souls to come back home – back to Godhead.

SP quotes from SB

(2.4.20) Śrīla Śukadeva Gosvāmī describes the Lord as pati in so many ways:

śriya patir yajña-pati prajā-patir
dhiyāṁ patir loka-patir dharā-pati
patir gatiś cāndhaka-vṛṣṇi-sātvatāṁ
prasīdatāṁ me bhagavān satāṁ pati

The prajā-pati is Lord Viṣṇu, and He is the Lord of all living creatures, all worlds, and all beauties, and the protector of everyone. The Lord created this material world to enable the conditioned souls to learn how to perform yajñas (sacrifices) for the satisfaction of Viṣṇu so that, while in the material world, they can live very comfortably without anxiety. After finishing the present material body, they can enter into the kingdom of God. That is the whole program for the conditioned soul. Through the performance of yajña, the conditioned souls gradually become Kṛṣṇa conscious and become godly in all respects. In the Age of Kali, the saṅkīrtana-yajña (the chanting of the names of God) is recommended by the Vedic scriptures.

Pati means master, husband or Lord.

So He is śriya patir – Lord of Goddess of fortune

yajña-pati – Lord of Yajna

prajā-patir – master of all living entities

dhiyāṁ patir – master of intelligence

loka-patir – master of all abodes

dharā-pati -master of earth

patir gatiś cāndhaka-vṛṣṇi-sātvatāṁ – and these are various dynasties in which Lord Krishna has appeared.

O Lord, you are the master of devotees, sātvatāṁ, transcendentalists.

Here, SP is quoting to emphasize that Praja-Pati refers to Lord Vishnu or Krishna, who is the Lord of everyone. This Praja-Pati has manifested, and He has given the system of Yajna. In Kaliyuga, we practice the system of Sankirtan Yajna. In this Yuga, Kali Yuga, He has further quoted about Lord Chaitanya:

Lord Kṛṣṇa, in His devotional form (as Lord Caitanya), is mentioned in the Śrīmad-Bhāgavatam (11.5.32) as follows, with special reference to the saṅkīrtana-yajña:

kṛṣṇa-vara tviṣākṛṣṇa
sāṅgopāṅgāstra-pāradam
yajñai sakīrtana-prāyair
yajanti hi su-medhasa

In this Age of Kali, people who are endowed with sufficient intelligence will worship the Lord, who is accompanied by His associates, through the performance of saṅkīrtana-yajña. Other yajñas prescribed in the Vedic literatures are not easy to perform in this Age of Kali, but the saṅkīrtana-yajña is easy and sublime for all purposes, as recommended in Bhagavad-gītā also (9.14).

kṛṣṇa-vara tvia + akṛṣṇa

kṛṣṇa-vara means this Lord is in same category as Krishna

tvia + akṛṣṇa, but His complexion is not like Krishna, it is different complexion

sāṅgopāṅgāstra-pāradam, sa + aga + upāṅga + astra-pāradam

aga, His limbs, upāṅga His sublimb, His astras all these are His Parsadam, so He has his associates with whom He comes

and what He do ?

yajñai sakīrtana-prāyair

So He teaches Sankirtan _Yajna

And su-medhasa

The intelligent people Medha is intelligent, su-medha is those who has good intelligence

Yajanti, they worship Him by performing Sankirtan Yajna.

So, Krishan has come as Chaitanya and taught Sankirtan Yajna, which we can perform to fulfill the purpose of Yajna.

So, what is the point discussed again? The point is that through Yajna, our needs are fulfilled; Yajna is the way to harmonize with the Supreme Lord. Yajna is the means by which our material and spiritual needs will be fulfilled. Let us try to understand how this happens.

It can refer to Brahmaji since he represents the Lord and is a secondary creator. Some Acharyas mentioned Brahma Ji, but Prabhupada said it is Vishnu, so there may be differences in details, but the essential principle remains the same.
