One’s memory of Krishna is revived by chanting the maha-mantra, Hare Krishna. By this practice of chanting and hearing the sound vibration of the Supreme Lord, one’s ear, tongue and mind are engaged.
Bhagavad-Gita 8.8,
Srila Prabhupada
In all circumstances we should try to chant the Hare Krishna maha-mantra while thinking, feeling, willing, breathing, hearing, seeing, speaking, touching, tasting, waking, passing, bathing, dressing, walking, sitting, driving, working, relaxing, sleeping, dreaming and dying.
Chanting the holy name without service attitude produces sound but no divinity – like a gun firing blanks, instead of bullets.
People want to play with their fingers and tantalize their eyes with Ipads, touch screens and play stations. Best to move your fingers on japa beads and fill your eyes with vraja-lila!
Swallow your ego and envy and digest it by chanting Hare Krishna.
Everyone says – "Chant these rounds, do this service, it's for your purification." What's the impurity? The impurity is our independence – not accepting that we are meant to serve Lord Krishna.
