Inspiring Buddhist Truths: All Beings have the Buddha Nature
No matter, what is happening in the world, remember the dignity of every human being; and feel the pains and sorrow of man, as in relation to your own. Remember, all mankind is suffering on various levels in this life.
དེ་བཞིན་ཉིད་དབྱེར་མེད་ཕྱིར་དང༌། །
རིགས་ཡོད་ཕྱིར་ན་ལུས་ཅན་ཀུན། །རྟག་ཏུ་སངས་རྒྱས་སྙིང་པོ་ཅན། །
“Because the perfect buddhas’s kaya is all-pervading,
Because reality is undifferentiated,
And because they possess the potential,
Beings always have the buddha nature.”
Maitreya, Sublime Continuum, I, 27.
“Although we are in samsara, we can still see proof of the existence of buddha nature permeating all living beings. [One] way in which we can discern whether beings have buddha nature is rik (Wyl. rigs; Skt. gotra), in other words the quality we perceive in one who possesses this buddha nature. […] All beings have buddha nature because all beings have within themselves what we call the essence of the buddha, this ju (Wyl. rgyu; Skt. hetu), this seed, which can blossom into a buddha and which constitutes our potential for enlightenment.”
Ringu Tulku Rinpoche, The Path to Buddhahood
