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. That devotion should be practised with steadiness and with an undesponding heart.
