Similarly, delights also may be experienced on the three planes.] ; so also, when he is vigata-sprhah, free from longing; sukhesu, for delights  when he, unlike fire which flares up when fed with fuel etc., has no longing for delights when they come to him ; and vita-raga-bhaya-krodhah, has gone beyond attachment, fear and anger.
