Does Not Give Instructions in Yoga to Outsiders [1]
X has sent a letter to you, which I enclose. He would like some upadeśa from you.
I do not usually give upadeśa like that. I believe he complains of an inability to concentrate his mind or feel bhakti, but that is not due to past karma and cannot be got rid of by any prāyaścitta — it is the inherent disability of the human mind that goes outward and not inward.
