6. DEVELOPING RENUNCIATION FOR SAMSARA
Purpose: To develop the realization of renunciation – the spontaneous wish to attain liberation from samsara.
Unless I attain liberation from samsara – the cycle of contaminated rebirth – I shall have to experience again and again, in life after life, endlessly, the sufferings of birth, sickness, ageing and death, having to part with what I like, having to encounter what I do not like, and failing to satisfy my desires.
Make the strong determination: “I must abandon samsara and attain the supreme inner peace of liberation.”
How do I abandon samsara I deeply ponder.
Be a good person.
I will be liberated.
