Patrul Rinpoche had said that absent genuine renunciation and bodhicitta, if one were to do a nine-year retreat and cut off all associations with others to practice the Great Perfection full-time, one would not even sow the seed of liberation, let alone other achievements. How terrible not having generated renunciation and bodhicitta! What use is there for other practices when not even the Great Perfection can sow the seed of liberation? Therefore, making the choice of motivation should never be taken lightly.
