Isserles, Moses ben Israel
or Rema
(
c.
1530–72). Jewish legal authority. Isserles was one of the great
halakhic
authorities of the time. He founded a
yeshivah
and gained a worldwide reputation for his
responsa
, being known as ‘the
Maimonides
of Polish Jewry’. Although he aroused opposition for his emphasis on custom (
minhag
) and his leniency (particularly when financial loss was involved), his rulings have become accepted as binding on
Ashkenazi
Jews.
Isshi-injo
(Jap., ‘one vehicle’). The Zen insistence that a student can be taught (up to the level of the conferring of
inka-sh
mei
) by one master (
roshi
) only. This is emphasized (especially in
S
t
-sh
) to stop students going from one teacher to another.
Isshin
(Jap., ‘one mind’). The universal mind which, in Buddhism, pervades all appearance—i.e. the Buddha-mind.
Issur ve-hetter
(Heb., ‘forbidden and permitted’). All Jewish legal rulings about forbidden food (see
DIETARY LAWS
).
