Sweet Mother,
What is meant by the yoga of devotion and the yoga of knowledge?
The yoga of knowledge is the path that leads to the Divine through the exclusive pursuit of the pure and absolute Truth.
The yoga of devotion is the path that leads to union with the Divine through perfect, total and eternal love.
In the integral yoga of Sri Aurobindo, the two combine with the yoga of works and the yoga of self-perfection to make a homogeneous whole, culminating in the yoga of supramental realisation.
