Shuranggama Sutra
ânanda, why is control of mind called sila? If all living beings
in the six worlds of existence abstain from sexual desire, they
will not be subject to the continual round of births and
deaths. Your practice of Samàdhi should free you from defilements
but they cannot be eliminated if your lustful mind
is not wiped out. Even after you have acquired such wisdom,
if you fail to kill sensuality, then when dhyàna manifests,
you will fall into the way of demons in which their king takes
the high, his male subjects the middle and his female subjects
the low rank. These demons have their following and boast
of having attained the Supreme Path. After my nirvàna, in
the Dharma ending age, these subjects of Màra will be found
everywhere, will encourage sensuality and will disguise
themselves as men of good counsel (kalyànamitras) and
cause living beings to fall into the pit of lust thereby missing
the Bodhi path.
You should teach worldly men who practise Samàdhi
to cut off their lustful minds at the very start. This is called the
Buddhas profound teaching of the first decisive deed.
Therefore, ânanda, if carnality is not wiped out, the practice
of dhyàna is like cooking gravel to make rice; even if it is
boiled for hundreds and thousands of aeons, it will be only
hot gravel. Why? Because instead of rice grains it contains
only stones. If you set your lustful mind on seeking the profound
fruit of Buddhahood, whatever you may realize will be
carnal by nature. If your root is lustful, you will have to transmigrate
through three unhappy ways (to the hells of fire,
blood and swords) from which you will not escape. How
then can you find the way to cultivate the Tathàgatas nirv
àna? You should cut off both the sensual body and mind
until even the very idea of doing so ceases; only then can you
hope to seek the Buddhas Enlightenment. This teaching of
mine is that of the Buddha whereas any other one is that of
evil demons (pàpiyàn).
