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.

(SB 7.5.23-24p)
