Chanting should be done in a way that the soul is an active witness.
Chanting is not just a process, it is a relationship. You and the holy name are together for two hours every day. If you are conscious of this while you chant, your chanting will dramatically improve.
Our quota is not sixteen rounds, but attentive sixteen rounds.
If one only chants, with some slight faith, the holy names of lord Chaitanya and Nityananda, very quickly he is cleansed of all offenses.
Even if one distributes ten million cows in charity during an eclipse of the sun, lives at the confluence of the Ganges and Yamuna for millions of years, or gives a mountain of gold in sacrifice to the brahmanas, he does not earn even one hundredth part of the merit derived from chanting Hare Krishna.
Keep up your endeavor for engaging in devotional service. Chanting the Holy Names is a vital point of devotional service. Be sure to improve on your quality of chanting. All other services are strongly supported by chanting of the Holy Name.
