The
p'rakim of
Birchos K'riyas Shema are as follows: the first blessing, the second blessing, the
parsha of
Shema, the
parsha of
V'haya im shamoa, and the
parsha of
Vayomer to the end of the blessing
Goal Yisroel. Since it is completely forbidden to interrupt (even with a pause of silence) between the words
Elokeichem (at the end of the
parsha Vayomer) and the word
emes (beginning the following blessing), the blessing
emes v'yatziv (in the morning) and
emes v'emunah (at night) are not considered separate
p'rakim. At night, the additional blessing
Hashkiveinu is a separate
perek. When reciting
K'riyas Shema to fulfill one's obligation without the blessings (e. g. when
shacharis will be later than the halachic time for
Shema), laws of interruption during the
p'rakim apply. In such a case, there is dispute among the
poskim whether the laws of
p'rakim will apply to the
K'riyas Shema recited for the second time with the blessings.
