Is bhakti alone sufficient for the attainment of God, for His vision?

Is bhakti alone sufficient for the attainment of God, for His vision?

Yes, one can see God through bhakti alone. But it must be "ripe" bhakti, prema-bhakti and raga-bhakti. When one has that bhakti, one loves God even as the mother loves the child, the child the mother, or the wife the husband.
