"Closing the gate to the lower realms (Apāyabhūmi) is an attainment in the mind level.One cannot achieve it by reading Dhamma books or doing certain good deeds, then assuming that he has reached the stage of enlightenment.If one wishes to close the gate to the lower realms, to be a Sotāpanna, he must practice Vipassana meditation."
