The practice of Purification of the Six Lokas is a special practice of purification from Dzogchen.
It is a powerful practice capable of eliminating not only the effects of negative karma, but especially its causes, namely disturbing emotions, such as anger or jealousy.
This practice also increases the clarity of the practitioner and removes obstacles. As this practice eliminates the causes of the emotions, it also prevents rebirth in the six realms of conditioned existence (lokas).
The attachment to delusional vision decreases and one is less conditioned by ordinary emotions. The Purification of the Six Lokas is especially important for Dzogchen practitioners because it facilitates the discovery of its instantaneous presence.
These practices are a precious power of healing and liberation, they are traditionally taught as preparation for Dzogchen.
