I would like to quote the "Liberation in the Palms of Your Hand" by Je Pabongkha Rinpoche.
THE DRAWBACK THAT YOU WILL NOT REMEMBER DHARMA
If you do not recollect death, you will think about only this life, get caught up in its many demands—food, clothes, and so on—and thus not practice Dharma. If you recollect death well, you will work hard to prepare for your next lives, just as a Khampa about to go on a journey would work only at preparing and packing. Your enormous craving for food, fashion, reputation, and so on, can be blamed on your not remembering impermanence. Every day that passes without your recalling impermanence is a day of your life wasted.
THE DRAWBACK THAT YOU WILL REMEMBER [THE DHARMA] BUT NOT PRACTICE IT
Je Tsongkapa said:
Everyone thinks, “Death will eventually come.” Yet they keep the evil thought, “But I will not die today, I will not die today,” right until they are on the point of dying.
So, the point is simple that we must start the practice immediately. Everybody we must at least practice Lojong, Lamrim and the 7 Limbs Prayers in any form.
