No difference between chanting for Kṛṣṇa consciousness and working for Kṛṣṇa consciousness.

The Kṛṣṇa consciousness movement is teaching people how to come to the stage of dedicating everything to the service of the Supreme Personality of Godhead. Kṛṣṇa says in Bhagavad-gītā (BG 9.27):

yat karoṣi yad aśnāsi
yaj juhoṣi dadāsi yat
yat tapasyasi kaunteya
tat kuruṣva mad-arpaṇam

“O son of Kuntī, all that you do, all that you eat, all that you offer and give away, as well as all austerities that you may perform, should be done as an offering unto Me.”

If whatever we do, whatever we eat, whatever we think and whatever we plan is for the advancement of the Kṛṣṇa consciousness movement, this is oneness . There is no difference between chanting for Kṛṣṇa consciousness and working for Kṛṣṇa consciousness. On the transcendental platform, they are one. But we must be guided by the spiritual master about this oneness; we should not manufacture our own oneness .

Why we should daily hear a Srila Prabhupada lecture

God is known to be unconquerable, but one who submissively hears the words of a self-realized soul conquers the unconquerable. The conclusion is that if one is serious about liberation, he not only should execute the occupational duties of varṇāśrama-dharma but should also engage in bhakti-yoga by beginning hearing from a realized soul. This process will help the devotee conquer the unconquerable Supreme Personality of Godhead and become His associate after giving up the material body.

(SB 4.24.53p)

The potency of hearing Srimad Bhagvatam

By sufficient hearing of Śrīmad-Bhāgavatam, the polluted aim of life, namely lording it over matter, will subside…By the process of bhakti-yoga, directly accepted by sufficient hearing of the transcendental message of the Lord, the material contamination is directly eliminated… And by practicing bhakti-yoga, if the performer is not purified from the material contamination, he must be a pseudodevotee. For such an imposter there is no remedy for being freed from material entanglement.

(SB 2.2.37p)

The all powerful, Holy name of the Lord

Therefore it is recommended:

harer nāma harer nāmaharer nāmaiva kevalamkalau nāsty eva nāsty evanāsty eva gatir anyathā

“In this age of quarrel and hypocrisy the only means of deliverance is chanting of the holy name of the Lord. There is no other way. There is no other way. There is no other way.”

Simply by chanting the holy name of the Lord, one advances perfectly in spiritual life. This is the best process for success in life.

In other ages, the chanting of the holy name is equally powerful, but especially in this age, Kali-yuga, it is most powerful. Kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet: (SB 12.3.51) simply by chanting the holy name of Kṛṣṇa, one is liberated and returns home, back to Godhead .

Therefore, even if one is able to perform other processes of devotional service, one must adopt the chanting of the holy name as the principal method of advancing in spiritual life.

Qualification to give the class

Srila Prabhupada- Lord Caitanya said that whether one is brahmana or whatever he may be if he knows the science of Krsna then he is to be accepted as guru. So one who gives class , he must read and study regularly and study the purport and realize it . Don’t add anything or concoct anything, then he can preach very nicely. The qualification for leading (the) class is how much one understands about Krsna and surrendering to the process .
