6 kinds of renunciation distress

Six kinds of renunciation distress:
The distress coming from the longing that arises in one who is filled with longing for the unexcelled liberations when, experiencing the inconstancy of those very forms, their change, fading, and cessation, he sees with right discernment as it actually is that all forms, past or present, are inconstant, stressful, subject to change and he is filled with this longing: 'O when will I enter and remain in the dimension that the noble ones now enter and remain in?' This is called renunciation distress. 
(Similarly with the other senses)
(from Majjhima Nikaya 137)
