In our Kṛṣṇa consciousness movement we therefore give special stress to the chanting of the Hare Kṛṣṇa mantra in all activities.

[Tamohara dasa ADMIN.]

"SB 8.23.16, Translation and Purport : There may be discrepancies in pronouncing the
mantras and observing the regulative principles, and, moreover, there may be discrepancies in regard to  time, place, person and paraphernalia. But when Your Lordship's holy name is chanted, everything becomes faultless. Śrī Caitanya  Mahāprabhu has recommended:
harer nāma harer nāma
harer nāmaiva kevalam
kalau nāsty eva nāsty eva
nāsty eva gatir anyathā

(CC 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." (Bṛhan-nāradīya
Purāṇa 38.126)
In this age of Kali, it is extremely difficult to perform Vedic ritualistic ceremonies or
sacrifices perfectly. Hardly anyone can chant the Vedic mantras with perfect pronunciation or accumulate the paraphernalia for Vedic performances. Therefore the
sacrifice recommended in this age is saṅkīrtana, constant chanting of the holy name of the Lord.
Yajñaiḥ
saṅkīrtana-prāyair yajanti hi
sumedhasaḥ (SB 11.5.29).
Instead of wasting time performing Vedic sacrifices, those who are intelligent,those who possess good brain substance, should take to the chanting of the Lord's holy name and thus perform sacrifice perfectly. I have seen that many religious leaders are addicted to performing yajñas and spending hundreds and thousands of rupees
for imperfect sacrificial performances. This is a lesson for those who unnecessarily execute such imperfect sacrifices. We should take the advice of Śrī Caitanya Mahāprabhu (yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ).
 
Although Śukrācārya was a strict brāhmaṇa addicted to ritualistic activities, he also
admitted, niśchidram anusaṅkīrtanaṁ tava:
"My Lord,constant chanting of the holy name of Your Lordship makes everything
perfect."
In Kali-yuga the Vedicritualistic ceremonies cannot be performed as perfectly as  before. Therefore Śrīla Jīva Gosvāmī has recommended that although one
should take care to follow all the principles in every kind of spiritual activity, especially in worship of the Deity, there is still a chance of discrepancies, and one should compensate for this by chanting the holy name of the Supreme
Personality of Godhead. In our Kṛṣṇa consciousness movement we therefore give special stress to the chanting of the Hare Kṛṣṇa mantra in all activities."
