Dear Victor and Dan, I quote the sutta in the PTs translation from an old
post. With Co notes. Dan will be interested to see notes on calm and
insight.
Nina.
We read in the Gradual Sayings, Book of the Fours( II, Ch XVI, §10, Coupled)
that Anada said :
Reverend sirs, when anyone, be it monk or nun, proclaaims in my presence
that he has attained arahatship, all such do so by virtue of four factors or
by one of these four. What are they?
Herein, your reverences, a monk develops insight preceded by calm. In him
thus developing insight preceded by calm is born the Way. He follows along
that Way, makes it grow, makes much of it… the fetters are abandoned, the
lurking tendencies come to an end.
Or again, your reverences, a monk develops calm preceded by insight. In him
thus developing calm preceded by insight is born the Way… the lurking
tendencies come to an end.
Yet again, your reverences, a monk develops calm-and-insight coupled. In him
thus developing… the Way is born… the lurking tendencies come to an end.
Once more, your reverences, a monk¹s mind is utterly cleared of perplexities
about dhamma. That is the time, your reverences, when his thought stands
fixed in the very self, settles down, becomes one-pointed, is composed. In
him the Way is born… the lurking tendencies come to an end.
The Co explains that the Way is the first stage of enlightenment. As to the
second factor, the monk is already used to developing insight and then
samadhi arises. As to the third factor, he is aware and considers the
sankharas, jhanafactors, in between the different stages of jhana he enters
and emerges from. As to the fourth factor, he has abandoned the ten
defilements of vipassana. He does not cling to samatha nor to vipassana.
It is interesting that there is no special order, a person¹s way of
development depends on his accumulations.
I discussed calm and insight with A. Supee in India. He reminded me that
whenever we read about calm, it is implied that it goes together with
insight. For some people the factor calm is stronger, for others less
strong. And as Kom explained, when insight is developed there are conditions
for more calm, in a natural way. The sotapanna has more calm than the
ordinary person, because he has less defilements. The sotapanna who has
developed insight has such strong, unshakable confidence in the Triple gem,
and when there are conditions he can have great calm while contemplating the
Buddha¹s virtues. Only ariyans could attain access concentration with this
meditation subject. The person who has attained the third stage of
enlightenment, the anagami, is no longer attached to sense objects, thus,
naturally, he has a great deal of calm.
When we read about the ideal Recluse, he goes forth with the aim to attain
arahatship, and becomes endowed with the highest qualities. Taken into
account that we are further away from the Buddha¹s time, we can draw our
conclusions to what extent all such high qualities are still possible. Then,
when we read about jhanas, we will understand all these passages in their
right perspective. No more doubts whether all of us should develop jhana.
