I know our movements during salah have specific meanings. For example our ruku' means that we are willing to be beheaded for Islam, our first sajdah that we came from soil etc.
Kindly explain me what are the specific meanings, if there are, of our tashhahud, salam, qunut, standing just after ruku' before going into sajdah and standing again between the end of a rakat and the beginning of the next.
