Question: Everyone says that Bhakti Yog is easy, while Gyān Yog is difficult. What is the reason for this?
Answer: Understand this by comparing a baby kitten and a baby monkey. The kitten is tiny in size and delicate in build. Yet if it is to be moved from one place to another, it does not need to worry. Its mother holds the kitten with her mouth and carries it. On the other hand, in the case of the baby monkey, the onus is not taken by the mother. While she jumps from one branch of the tree to another, it is the baby monkey's responsibility to hold its mother tightly, else she will fall.
Bhakti Yog is comparable to the cat and its kitten. In Bhakti Yog, the aspirant learns to surrender to the Lord, and thus attracts His Grace. Through Grace, God assists and protects the devotee. Thus, the path of Bhakti Yog becomes easy compared to Gyān Yog.
In Gyān Yog, the danger of pride is enormous. The poor conditioned soul gets trapped in the ego of being God. In comparison, the path of Bhakti involves practicing humbleness before God, and hence the pitfall of pride becomes marginalized.
