If you think of one God , sing and hear his glories only , mingle with HIS devotees and do service only to him, your mind would attain one-pointedness
Why did he say that one should dance about on the streets (singing the glory of the Lord)?
Immediately that dumb boy gained divine knowledge and started dancing, singing the Divine Names, `Rama' and `Krishna'

Hare Rama Hare Rama Rama Rama Hare Hare
Hare Krishna Hare Krishna Krishna Krishna Hare Hare
