Even in the lowest stage the karmis are advised to work for the Lord-SP

As stated in Bhagavad-gītā (18.3), yajña–dāna–tapaḥ–karma na tyājyam: the Vedic ritualistic ceremonies, charity, austerity and all such prescribed duties are never to be given up. Yajño dānaṁ tapaś caiva pāvanāni manīṣiṇām (18.5): even one who is very much advanced in spiritual realization must still execute the Vedic principles. Even in the lowest stage, the karmīs are advised to work for the sake of the Lord.yajñārthāt karmaṇo ’nyatra
loko ’yaṁ karma–bandhanaḥ“Work done as a sacrifice for Viṣṇu has to be performed, otherwise work binds one to this material world.” (Bg. 3.9) The words yajñārthāt karmaṇaḥ indicate that while performing all kinds of duties, one should remember that these duties should be performed to satisfy the Supreme Lord (sva–karmaṇā tam abhyarcya). According to Vedic principles, there must be divisions of human society (cātur–varṇyaṁ mayā sṛṣṭam [Bg. 4.13]). There should be brāhmaṇas, kṣatriyas, vaiśyas and śūdras, and everyone should learn to worship the Supreme Personality of Godhead (tam abhyarcya). This is real human society, and without this system we are left with animal society.The modern activities of human society are described in Śrīmad-Bhāgavatam as the activities of go-khara, cows and asses (sa eva go-kharaḥ [SB 10.84.13]). Everyone is acting in a bodily concept of life involving society, friendship and love for the improvement of economic and political conditions, and thus all activities are enacted in ignorance. The Supreme Personality therefore comes to teach us how to act according to the Vedic principles. In this age of Kali, the Supreme Personality of Godhead appeared as Śrī Caitanya Mahāprabhu and preached that in this age the Vedic activities cannot be systematically performed because people are so fallen. He gave this recommendation from the śāstras:harer nāma harer nāma
harer nāmaiva kevalam
kalau nāsty eva nāsty eva
nāsty eva gatir anyathā
[Adi 17.21]“In this age of quarrel and hypocrisy the only means of deliverance is chanting the holy name of the Lord. There is no other way. There is no other way. There is no other way.” …We should learn how to act from Bhagavad-gītā, which explains everything for human understanding. Thus we can become happy even in this age of Kali.

Some Conclusions–in this purport SP tells us….Even in the lowest stage, the karmīs are advised to work for the sake of the Lord. So we all know Krsna takes us in His BG thru the steps of advancing in spiritual life-from karma yoga, to jnana yoga ultimately to bhakti yoga, which is the highest of all dharmas. And even karma yoga is no small feat as we can see below…

Prabhupada: Karma-yogi means one who does everything for Krsna. He’s
karma-yogi.
Guest (1): One who does everything for…?
Prabhupada: For Krsna.
Guest (1): For Krsna.
Prabhupada: Just like you are doing, doing some work. For whom you are
doing?
Guest (1): For my own benefit.
Prabhupada: That’s all. So that is karma. But when you do the same
thing for Krsna, that is karma-yoga.Prabhupada: That’s all. (break) …done not meant for Krsna, that is
for his own satisfaction. Just like Arjuna wanted to become
nonviolent: “No, no, Krsna. I cannot kill my kinsmen.” That is a good
proposal. But that was his satisfaction.
Guest (1): That is very correct.
Prabhupada: Yes. That was his satisfaction. But Krsna wanted that “You
must fight.” And when he agreed to that, that is his perfection.
Before that, he was trying to satisfy he.
… Whatever you do, that is your satisfaction. That is karma.
Guest (1): But not yogi.
Prabhupada: No, karma. (break) …for your own sense satisfaction,
that is karma. And if you do it for Krsna’s satisfaction, that is
karma-yoga.Makhanlal: Pure bhakti and karma-yoga considered to be exactly the
same?
Prabhupada: Exactly the same.
Prabhupada: Pure bhakti is above karma-yoga. Pure bhakti is above
karma-yoga.
Bhagavata: That is the difference between the Chapter Karma-yoga and
Karma-yoga in Krsna Consciousness.
Prabhupada: Yes. Pure, pure devotion means Sravanam kirtanam.
Makhanlal: …you’re performing, is the vaidhi-bhakti stage of…
Prabhupada: Yes.
Makhanlal: …of the sadhana-bhakti, the regulative principles.
Prabhupada: Yes, vaidhi-bhakti means regulative principles, and when
you are accustomed, automatically you perform, that is raga-bhakti.
Makhanlal: So vaidhi-bhakti is considered superior to karma-yoga then.
Prabhupada: No. Karma-yoga is better.
Makhanlal: Karma-yoga is better?
Prabhupada: Yes.Indian man: Pure bhakti is superior.
Prabhupada: Pure bhakti is sravanam kirtanam. Sravanam kirtanam
visnu-smaranam pada-sevanam, that is pure bhakti. (break)
Yasomatinandana: …formed by anybody.
Prabhupada: Eh?
Yasomatinandana: Karma-yoga.
Prabhupada: Unless one is inclined to take to devotion, it is not
possible to take to karma-yoga. Who can sacrifice the profit?
Yasomatinandana: Does karma-yoga mean to follow exactly the sastras?
Prabhupada: Karma-yoga means yat karosi yaj juhosi kurusva tat
mad-arpanam.———————————So this means if we are not giving 50% of our hard earned wealth to God, then we are not real bhaktas but lower than karma yogis- who do so.This is the formula that Srila Prabhupada has given to us.Prabhupada: Karma-yogi means one who does everything for Krsna. He’s karma-yogi.
