The process of chanting the holy name of the Lord is so powerful that by this chanting even householders can very easily gain the ultimate result achieved by person in the renounced order. — Srimad Bhagavatam, 07.15.74
Krishna is present fully in His holy name and this is realized by the humility and sincerity in our chanting.
Detachment means to not be owned by what we own.
If one wants to derive the actual benefit from this human form, he must take to the chanting of the holy name of the Lord.
Srimad Bhagavatam 7.6.19,
