5 Four conditions must meet for the arising of kàya-dvàravãthi.
They are:
i Kàya-pasàda (body-door) must be good,
ii Phoññhabbà-rammaõa (touch) must be present,
iii Thaddha-pathavà (firm solid element) must be present
for transmittance of the touch,
iv Manasikàra (attention) must be present.
6 Four conditions must meet for the arising of mano-dvàravãthi.
They are:
i Mano-dvàra (mind-door) must be present,
ii Dhammà-rammaõa (mind-object) must be present,
iii Hadaya-vatthu (heart-base) must be present,
iv Manasikàra (attention) must be present.
Note:
Of the four causes which are required for the arising of
each type of vãthi, the first three more or less parallel the
requirements known by science. The fourth cause, i.e.,
manasikàra, is unknown in science. But many instances may
be quoted that this cause is indispensable for the awareness
of a sense-object.
For illustration, a mother with a young baby has to get
up several times every night to nurse her baby. After losing
sleep for several nights, she may, sometimes, fall so soundly
asleep that even a loud thunder that shakes the house may
not awake her. Yet, if her baby cries very softly, she will be
immediately awake. This illustrates how important
manasikàra is.
