Jnana and Bhakti are two different paths towards one Truth. Jnana is the path of Contemplation and Inquiry while Bhakti is the Path of Surrendering to the highest entity, Bhagawan. In Kaliyuga it is difficult to apply our intelligence through the path of Self-Inquiry which requires a Razor Sharp intellect to grasp the nature of the Self. On the otherhand if we take up to Bhakti, Bhagawan will easily hold our hands and lead the way. He shall present a Guru and also clear the path towards Sel-realization and Ultimately God-realization. Hence, in Kaliyuga Bhakti alone is the superior path.
