又增一阿含經云。爾時世尊告諸比丘。有三因緣識來受胎。一母有欲父有欲父母共集一處。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。母不大殷勤則非成胎。三若父母共集一處。母欲熾盛父不大殷勤。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 says: At that time, the World-Honoured One addressed the monks: 'There are three causes and conditions through which consciousness comes to take conception in the womb: First, the mother has desire, the father has desire, and the parents come together in one place; yet if the consciousness from without should not yet approach, conception does not take place. If the consciousness approaches, but the parents do not come together, conception likewise does not take place. Second, if the mother has no desire while the father's desire is intense, and the mother is not earnest, conception does not take place. Third, if the parents come together in one place, and the mother's desire is blazing while the father is not earnest, conception does not take place. Furthermore, there are three [other] types: First, if the parents come together in one place, but the father suffers from a wind disease and the mother from a cold disease, conception does not take place. Second, if the mother suffers from a wind disease and the father from a cold disease, conception does not take place. Third, if the father's body has an excess of water humours while the mother has no such ailment, conception does not take place. Furthermore, there are three types: First, if the parents come together in one place, but the father's bodily signs indicate offspring while the mother's bodily signs indicate no offspring, conception does not take place. Second, if the mother's bodily signs indicate offspring while the father's bodily signs indicate no offspring, conception does not take place. Third, if both parents' bodily signs indicate no offspring, conception does not take place. Furthermore, there are three types: First, if at times the conscious spirit approaches the womb, but the father is away on a journey and not present, conception does not take place. Second, if at times the parents ought to come together in one place, yet the mother is away on a distant journey and not present, conception does not take place. Third, if the parents both come together and do not travel, then conception takes place. Furthermore, there are three types: First, if at times the parents ought to come together in one place, but the father's body suffers from severe illness, then when the conscious spirit comes to approach, conception does not take place. Second, if the mother's body suffers from severe illness, conception does not take place. Third, if both parents' bodies fall ill, conception does not take place. If the parents have no ailments, the conscious spirit comes to approach, and both parents have bodily signs indicating offspring, then conception does take place.'
