The scriptures speak very clearly and repeatedly on this point:
๐ฉ๐ข๐ณ๐ฆ๐ณ ๐ฏฤ๐ฎ๐ข ๐ฉ๐ข๐ณ๐ฆ๐ณ ๐ฏฤ๐ฎ๐ข ๐ฉ๐ข๐ณ๐ฆ๐ณ ๐ฏฤ๐ฎ๐ข ๐ฆ๐ท๐ข ๐ฌ๐ฆ๐ท๐ข๐ญ๐ข๐ฎ

(ล๐ณฤซ ๐๐ข๐ช๐ต๐ข๐ฏ๐บ๐ข-๐ค๐ข๐ณ๐ช๐ตฤ๐ฎแน๐ต๐ข ๐๐ข๐ฅ๐ฉ๐บ๐ข 6.242)
โโIn the Age of Kali, the Holy Name of Hari alone, the Holy Name alone, the Holy Name alone is everything. There is no other way, no other way, no other way.โ
Again it is declared:
๐ฌฤซ๐ณ๐ต๐ข๐ฏฤ๐ฅ ๐ฆ๐ท๐ข ๐ฌแนแนฃแน๐ข๐ด๐บ๐ข ๐ฎ๐ถ๐ฌ๐ต๐ข-๐ด๐ขแน

(ล๐ณฤซ๐ฎ๐ข๐ฅ ๐๐ฉฤ๐จ๐ข๐ท๐ข๐ต๐ข๐ฎ 12.3.51)
โโSimply by chanting the Name of Kแนแนฃแนa, one becomes liberated and attains the supreme destination.โ
And further:

(ล๐ช๐ฌแนฃฤแนฃแนญ๐ข๐ฌ๐ข๐ฎ 2)
โโO Lord, You have invested all Your divine potencies in Your Holy Names, and there are no rules regarding the time for remembering them.โ
Our Guru-varga, including ลrฤซla Bhakti Siddhฤnta Saraswatฤซ แนฌhฤkur Prabhupฤd, have established that the Name is ๐ด๐ท๐ข๐บ๐ข๐ฎ-๐ด๐ช๐ฅ๐ฅ๐ฉ๐ข (self-perfect) and ๐ฑลซ๐ณแน๐ข (complete). It does not depend on any external addition. However, they have also taught that to realise the full potency of the Name, one must chant under proper guidance, avoiding offences and following a disciplined life.
Spiritual life is not a matter of inventing new ๐ฎ๐ข๐ฏ๐ต๐ณ๐ข๐ด or substituting revealed truths with personal preference. It is a matter of receiving what descends through Guru-paramparฤ. Therefore, I humbly but firmly submit: Hari-nฤm is complete, sufficient, and divinely ordainedโour duty is not to replace it, but to surrender to it.
