What is the purpose of singing Kirtans constantly?

Singing of Kirtans incessantly will produce divine vibrations within and these vibrations
are so powerful as to counteract all external forces distracting the human mind and arrest the
wanderings of the mind, bringing peace and happiness to the individual. There is a mysterious
power in the Divine Name that singing it purifies the heart and mind and makes the Kirtanist
God-conscious.

How can a person, who has been thinking in a negative way for a long time, change to positive thinking?

Let him start with some positive suggestive formulas: “I am hale and hearty. I am
healthy. There is nothing wrong with me. I was under a misconception of my own abilities and
capacities. Now I have realized my real nature”. Let him do it with the help of some person
advanced in Yoga or a devotee of the Lord. Let him start with a prayer to the Lord. Let him
make prayer a part of his daily life and ‘a must’ in life. All negative thinking will end and he will
become quite normal.
