Some people have a very powerful relationship with God built on devotion. This path of Bhakti, can by some be looked upon as duality, but this duality removes separateness and is full of humility. It opens the heart and is beyond merely human love.
Jnana - the path of wisdom and self- inquiry, in combination with Bhakti, are like the two wings of the same bird. Both wings are needed for the bird to fly.
