By chanting the glories of the Supreme Personality of Godhead in the association of devotees, one becomes satisfied and happy and develops a loving friendship with the devotees. In this way one becomes able to give up material sense gratification, which is the cause of all suffering. When a devotee attains the stage of pure love of Godhead, the hairs of his body stand on end, and he manifests various ecstatic symptoms; he personally meets the Supreme Lord and becomes full of transcendental bliss. By learning the science of devotional service and practically engaging in the devotional service of the Lord, the devotee comes to the stage of love of Godhead. When completely devoted to the Supreme Personality of Godhead, Nārāyaṇa, the devotee easily crosses over the illusory energy, māyā, which is extremely difficult to cross.
