又增一阿含經云。爾時世尊。告諸比丘。有三因緣。識來處受胎。一母有欲。有父母共集一處。然外識未應來趣。便不受胎。若識來趣。父母不集則不成胎。二若復母人無欲。父欲意盛。母不大慇懃則非成胎。三若父母共集一處。母欲熾盛。父不大慇懃則非成胎。復有三種。一若父母共集一處。父有風病。母有冷病。則非成胎。二若母有風病。父有冷病。則非成胎。三若父身。水氣偏多。母無此患。則非成胎。復有三種。一若父母共集一處。父相有子。母相無子。則不成胎。二若母相有子。父相無子。則不成胎。三若父母俱相無子。則非成胎。復有三種。一若復有時。識神趣胎。父行不在。則非成胎。二若有時。父母應集一處。然母遠行不在。則不成胎。三父母俱集不行。此則受胎。復有三種。一若有時父母應來集一處。然父身遇重患。有時識神來趣。則非受胎。二若母身得重患。則非成胎。三若父母身俱得病。則非成胎。若父母無患。識神來趣。然父母俱相有兒。則成有胎。

Furthermore, the Ekottarika-āgama states: At that time, the Bhagavat addressed the bhikṣus: 'There are three causes and conditions for consciousness to come to the place and take conception. First, the mother has desire, and the parents come together in one place, yet the external consciousness is not yet due to arrive, then conception does not take place; if consciousness arrives, but the parents do not come together, a fetus is not formed. Second, if the mother has no desire while the father's desire is intense, and the mother is not very earnest, then a fetus is not formed. Third, if the parents come together in one place, and the mother's desire is blazing while the father is not very earnest, then a fetus is not formed. Furthermore, there are three types: first, if the parents come together in one place, the father has a wind illness and the mother has a cold illness, then a fetus is not formed; second, if the mother has a wind illness and the father has a cold illness, then a fetus is not formed; third, if in the father's body water-qi is predominantly excessive while the mother does not have this affliction, then a fetus is not formed. Furthermore, there are three types: first, if the parents come together in one place, the father's physiognomy indicates children while the mother's physiognomy indicates no children, then a fetus is not formed; second, if the mother's physiognomy indicates children while the father's physiognomy indicates no children, then a fetus is not formed; third, if both parents' physiognomies indicate no children, then a fetus is not formed. Furthermore, there are three types: first, if at a time when the conscious spirit approaches the womb, the father is traveling and absent, then a fetus is not formed; second, if at a time when the parents ought to come together in one place, the mother is traveling far away and absent, then a fetus is not formed; third, if the parents are together and not traveling, then conception occurs. Furthermore, there are three types: first, if at a time when the parents ought to come together in one place, the father suffers from a severe illness, even if at that time the conscious spirit approaches, conception does not occur; second, if the mother suffers from a severe illness, then a fetus is not formed; third, if both parents suffer from illness, then a fetus is not formed. If the parents are without affliction, the conscious spirit approaches, and both parents' physiognomies indicate children, then a fetus is formed.'
