I am very much encouraged to learn that you are bold enough to challenge any nondevotee as you did with that impersonalist yoga student. That should be the temperament of all our preachers. We should not be aggressive, but we should not tolerate any sort of nonsense. One who says that God is not merciful because He has made one person happy and one distressed is most nonsensical. This very statement affirms that man as a godless rascal. All of these so-called yogis are therefore rascals because they have no actual realization of God. Falsely they think themselves as God, and their association should be avoided as far as possible.
