Chanting the holy name is the basic principle of spiritual advancement:

[Lord Kapila to Devahuti]: "A devotee should always try to hear about spiritual matters and should always utilize his time in chanting the holy name of the Lord. His behavior should always be straightforward and simple, and although he is not envious but friendly to everyone, he should avoid the company of persons who are not spiritually advanced."

".. It is especially mentioned here, nāma-saṅkīrtanāc ca: one should chant the holy names of the Lord—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—either individually or with others. Lord Caitanya has given special stress to chanting of these holy names of the Lord as the basic principle of spiritual advancement. .." - (Srimad-Bhagavatam 3.29.18, by His Divine Grace)
