Therefore, philosophy does not give sense in mind happiness. It keeps in mind the only truth. However, it is very possible that the truth may be painful, may be distressing, may be destructive of happiness or makes it impossible. Religion, unlike philosophy, is under the category of the useful one. It promises happiness and says what it is necessary to do and what it is necessary to be to deserve or to obtain it. Consequently, illusion is more important than truth if it gets happiness.
