Holy Woman

The reason a mother who gives birth is called a חיה is because it was very common for women to die during childbirth. She, having survived is called the live one.חיה Women, who died during childbirth, were buried in a separate area of the Bais Hachayim. The Shu”t Divrei Malkiel (2:94) writes, the reason for it was because we find in the Gemoro (Shabbos 118b) R.Yosi said on himself, he wishes to die on the way to do a Mitzvah. Women while giving birth is like on the way to a Mitzvah. Dying during childbirth is like dying על קידוש השם. They are on a higher level than the rest and need to be buried separately." *Perhaps, this might be an additional reason, for Rochel to be buried separately and not with the אמהות  because she died during childbirth, she was at a different & higher level than the  אמהות This might also be the reason קבר רחל is so special. Chazal say those who die על קידוש השם אין אחרות נכנסות במחיצתן therefore we try to get physically as close as possible while we still can. R. Chaim Shmulevits zt"l encouraged Talmidim, instead of traveling to קברי צדיקים to go locally to  קברים of holy soldiers who died על קידוש השם. * (אמבצי)
