Maybe you have received teaching called the purification of the six lokas. There are many different versions of this practice and it is a characteristic purification in the Dzogchen teaching.

Basically we have five emotions. When we apply each of them, then we produce one of the six lokas. For example, if we are continually angry and we do not purify [that emotion], we accumulate that cause of the vision of hell more and more. If, for example, we ask where hell is, today, in this moment, we cannot find it anywhere, but we cannot say that it doesn’t exist because we have its cause.

Day after day, year after year, we accumulate emotions. If we continue to accumulate emotions such as anger and do not purify [them], then we will have a very rich accumulation of the cause. In this moment we do not have a vision of hell because we are being and we live in the human condition, and our dimension is human karmic vision. However, when we finish our human vision, we die and are in the state of bardo, which is the intermediate state for all sentient beings. But after the bardo of existence, we go after the potentiality of our karma, that is, the kind of accumulation we have that is strongest. Not one of us is free.
