Children are passionate to learn & play interacitve games at an early age, similarly, Krishna Consciousness should also start at an early age.
A man bound by the hands and feet cannot free himself. He must be helped by a person who is unbound because the bound cannot help the bound, the rescuer must be liberated. Therefore, only Lord Krishna or His bona fide representative can release the conditioned soul.
Let people chant the Hare Krsna mantra constantly. Then their demoniac tendencies will be killed, and they will become first-class devotees, happy in this life and in the next.
Srimad Bhagavatam 6.2.14,
