The Second Treatise on the Perfections – 2872
of the fourth absorption, are the same in their ultimate sense. They are all
mental concomitants that are specific neutrality (
tatra-majjhattatā-cetasika
).
Why are they then enumerated as six kinds? Because they differ from one
another in their time of arising. A simile is given in the above-quoted
commentaries to explain this point: A man, in his childhood, is called a boy
(
kumāra
); when he becomes older, he is called a youth (
yuva
); again, when he
becomes older, he is called an adult (
vuddha
), general (
senāpati
), king (
rāja
), etc.
A man is thus called differently according to the stages and positions in his life.
To make it clearer, their distinctions are due to the differences in their functions,
which are as follows:
1. As has been stated before, to contemplate all six sense objects, good and bad,
with equanimity is the function of equanimity with six factors (
chaḷaṅgupekkhā
).
2. To contemplate the happiness and suffering of beings with equanimity is the
function of equanimity as sublime living (
Brahma-vihārupekkhā
).
3. In striving to achieve the absorptions (
jhāna
), path and fruition states, to
contemplate with equanimity the hindrances that are to be removed is the
function of equanimity as a factor of Awakening (
Bojjhaṅgupekkhā
).
4. To develop energy neither too much nor too little than what is required is the
function of equanimity of effort (
viriyupekkhā
).
5. To contemplate with equanimity all correlated factors, without encouraging
or suppressing is the function of equanimity regarding formations
(
saṅkhārupekkhā
).
6. To contemplate sensations with equanimity is the function of equanimity
regarding feelings (
vedanupekkhā
).
7. To contemplate with equanimity the three characteristics of impermanence
(
anicca
), suffering (
dukkha
) and non-self (
anatta
) is the function of equanimity
resulting from insight (
vipassanupekkhā
).
8. To contemplate with equanimity the associated factors which are well
balanced is the function of equanimity as specific neutrality (
tatra-
majjhattupekkhā
).
