I am envious offender, I will not say anything, I will just quote Prabhupada and post videos made by pure devotees.

CC Adi, chapter 17


In this Age of Kali, the holy name of the Lord, the Hare Kṛṣṇa mahā-mantra, is the incarnation of Lord Kṛṣṇa. Simply by chanting the holy name, one associates with the Lord directly. Anyone who does this is certainly delivered.


This verse repeats the word ‘eva’ [‘certainly’] three times for emphasis, and it also three times repeats ‘harer nāma’ [‘the holy name of the Lord’], just to make common people understand.


The use of the word ‘kevala’ [‘only’] prohibits all other processes, such as cultivation of knowledge, practice of mystic yoga, and performance of austerities and fruitive activities.

PURPORT: Our Kṛṣṇa consciousness movement stresses the chanting of the Hare Kṛṣṇa mantra only, whereas those who do not know the secret of success for this Age of Kali unnecessarily indulge in the cultivation of knowledge, the practice of mystic yoga or the performance of fruitive activities or useless austerities. They are simply wasting their time and misleading their followers. When we point this out very plainly to an audience, members of opposing groups become angry at us. But according to the injunctions of the śāstras, we cannot make compromises with these so-called jñānīs, yogīs, karmīs and tapasvīs. When they say they are as good as we are, we must say that only we are good and that they are not good. This is not our obstinacy; it is the injunction of the śāstras. We must not deviate from the injunctions of the śāstras. This is confirmed in the next verse of Caitanya-caritāmṛta.


This verse clearly states that anyone who accepts any other path cannot be delivered. This is the reason for the triple repetition ‘nothing else, nothing else, nothing else,’ which emphasizes the real process of self-realization.
