The single qualification for entering the kingdom of God
Lord Caitanya recommended the feeling of the gopis as the highest mode of worship that can be rendered to the Lord. The conclusion is that the regular practice of bhakti-yoga will lead the devotee to the plane of intense love for the Lord, and that is the single qualification by which the conditioned soul is allowed to reenter the eternal life of bliss in the kingdom of God.
from Light of the Bhagavata by Srila Prabhupada
