That (mental condition), in which the mind restrained by practice, of abstraction, ceases to work; in which too, one seeing the self by the self, is pleased in the self; in which one experiences that infinite happiness which transcends the senses, and which can be grasped by the understanding only; and adhering to which, one never swerves from the truth; acquiring which, one thinks no other acquisition higher than it; and adhering to which, one is not shaken off even by great misery; that should be understood to be called devotion in which there is a severance of all connexion with pain.
