If someone is not qualified for Karma Yoga he can practice Karma Kanda:
1-10: KY is better for you as you are not qualified for JY (of course Arjuna is a pure devotee and he is qualified for more than JY but in this context when Krishna is giving instructions at progressive levels and the level He is talking for if one is not qualified then JY can create disruption in society, can make one hypocritical and can make one’s livelihood also 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
saha-yajnah prajah srishtva
esha vo 'stv ishta-kama-dhuk
saha -- along with; yajnah -- sacrifices; prajah -- generations; srishtva -- creating; pura -- anciently; uvaca -- said; praja-patih -- 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; kama-dhuk -- bestower.
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. Prajapati, 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 referring to actually?
Krishna is telling the system of Yajna is there right from the beginning to creation. So when creation is made just like when Parents beget a child they arrange for taking care of the child. So similarly when Lord creates living being He makes arrangement to take care for them, what is that arrangement – it is system of Yajna so Yajna is esha vo 'stv ishta-kama-dhuk, let this be fulfiller of your desires, so in these verses Krishna talks about system of cosmic cooperation between the devatas, the Supreme Lord and the human beings, this will be discussed little later, so here we will discuss when Lord creates he doesn’t send living entities to wilderness we can see this how Lord arranges through nature, e.g. when a baby is born, food for child is arranged in the womb, milk is available through mother and all species everyone in this world gets their food. So how they get that? That is arranged by the Supreme Lord. So in this way this universe is perfectly complete. So the Lord has arranged to care for the needs of living beings.
Animals doe not have any karmic result they largely acts on their instincts for the sake of eating sleeping mating and defending, In human life we have advance level of consciousness we have capacity to regulate eating, sleeping, mating and defending and we have capacity to choose and so we can redirect our desire to choose spiritual desires, for human beings also Krishna provides necessaity of life but we have responsibility to discharge our material duty 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:
śriyaḥ patir yajña-patiḥ prajā-patir
dhiyāṁ patir loka-patir dharā-patiḥ
patir gatiś cāndhaka-vṛṣṇi-sātvatāṁ
prasīdatāṁ me bhagavān satāṁ patiḥ
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, and after ﬁnishing the present material body they can enter into the kingdom of God. That is the whole program for the conditioned soul. By 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 śriyaḥ patir – Lord of Goddess of fortune
yajña-patiḥ - Lord of Yajna
prajā-patir – master of all living entities
dhiyāṁ patir – master of intelligence
loka-patir – master of all abodes
dharā-patiḥ -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.
So here SP is quoting to point that Praja-Pati refers to Lord Vishnu or Krishna who is Lord of everyone. And this Praja-Pati has manifested and He has given the system of Yajna and 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:
yajanti hi su-medhasaḥ
“In this Age of Kali, people who are endowed with sufﬁcient intelligence will worship the Lord, who is accompanied by His associates, by 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-varṇaṁ tviṣa + akṛṣṇaṁ
kṛṣṇa-varṇaṁ means this Lord is in same category as Krishna
tviṣa + akṛṣṇaṁ, but His complexion is not like Krishna, it is different complexion
sāṅgopāṅgāstra-pārṣadam, sa + aṅga + upāṅga + astra-pārṣadam
aṅga, 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 ?
So He teaches Sankirtan _Yajna
The intelligent people Medha is intelligent, su-medha is those who has good intelligence
Yajanti, they worship Him by performing Sankirtan Yajna.
So He has come and taught Sankirtan Yajna which we can perform and fulfill the purpose of Yajna.
So Here what is the point talked about again? The point is through Yajna our needs are fulfilled, Yajna is the way to harmonize with Supreme Lord. And Yajna is the means by which out material and spiritual needs will get fulfilled. So let is try to understand how this happens?
So it can refer to Brahmaji since he represents Lord and He is a secondary creator. Some Acharyas mentioned Brahma Ji but Prabhupada said it is Vishnu so there may be difference in details but essential principle remains the same.
