In this age no process of realizing the Supreme is possible except the chanting of the holy names of Lord Krishna: Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
The Supreme intelligence behind all creation is the Absolute Godhead, Sri Krishna.
Those who perform severe austerities and penances, those who give away all their possessions out of charity, those who are very famous for their auspicious activity, those who are engaged in meditation and mental speculation and even those who are very expert in reciting the Vedic mantras are not able to obtain any auspicious result, although they are engaged in auspicious activities, if they do not dedicate their activities to the service of the Supreme Personality of Godhead. — Sri Caitanya Caritamrita, Madhya Lila, 22.20.
There is no question of darkness where there is light and Krishna Consciousness is the light that dispels the darkness of material sense enjoyment.
