俱舍論頌疏論本 18.108

18.108

釋曰：趣、苦、恩、德四田不同，名為田異。由趣別者，若施傍生受百倍果，施犯戒人受千倍果，是名趣異。由苦別者，謂七有依福，濟他苦故，福不可量：一、施行路人。二、施羈旅客。三、施病者。四、施看病人。五、施寺園林。六、施常食，西國信士於遠絕處，恐行侶飢餓，造舍置財，多貯飲食，通施一切。或有但標供出家者，常施食故，名施常食。七、隨時施者，於寒熱風隨時施彼故。

The commentary says: The four fields of destiny (gati), suffering (duḥkha), beneficence (upakāra), and virtue (guṇa) being different is called "distinctions in the field." Due to distinction in destiny: giving to animals receives a hundredfold fruit, while giving to a person who has broken the precepts receives a thousandfold fruit; this is called distinction in destiny. Due to distinction in suffering: this refers to the seven material meritorious actions, which, because they relieve the suffering of others, have immeasurable merit: 1. giving to travelers; 2. giving to guests far from home; 3. giving to the sick; 4. giving to caretakers of the sick; 5. giving monasteries and parks; 6. giving constant food: faithful laymen in the Western regions, fearing travelers might starve in remote places, construct buildings, set up funds, store ample food and drink, and provide universally to all; or some specifically designate it for offering to renunciants, and because food is constantly given, it is called giving constant food; 7. giving according to the season: giving to them according to cold, heat, or wind.
