Q: What is the proper function of the intellect? Is it helpful in Sadhana?
Its function is to reason from the perceptions of the mind and senses, to form conclusions and to put things in logical relation with each other. A well-trained intellect is a good preparation of the mind for greater knowledge, but it cannot itself give the Yogic knowledge or know the Divine — it can only have ideas about the Divine, but having ideas is not knowledge. In the course of the sadhana intellect has to be transformed into the higher mind which is itself a passage towards the true knowledge.
