If you study powa (Skt. saṃkrānti, the yoga of mindstream transference to the Pure Land), then at the time when death is approaching you will know no despair. If beforehand you have become accustomed to the path of powa, then at the time of death you will be full of cheerful confidence. —Marpa
By the time we are about to enter the bardo, the intermediate state between death and birth, it will be far too late to begin our Dharma practice. But if we have already prepared ourselves, if we feel confident in our practice and know how to go to a Buddha-field, there will be no suffering in death.
