Doctors for ailing Israeli Prime Minister Ariel Sharon have begun discussions on his condition.
Worshippers are holding a round-the-clock vigil

Mr Sharon, 77, suffered a big stroke on Wednesday and has had three operations to stop bleeding on his brain.
A spokesman for Jerusalem's Hadassah Hospital said early
on Sunday that Mr Sharon remains in a critical but stable condition,
with no overnight change.
Doctors must now decide whether to bring him out of a drug induced coma, after detecting small improvements.
A brain scan on Saturday revealed minor improvements in
his condition, but the full extent of any brain damage or physical
disability he may have suffered can only be understood by reducing
sedation.
Meanwhile acting Prime Minister Ehud Olmert will chair Israel's weekly cabinet meeting on Sunday morning.
Despite the ongoing crisis over Mr Sharon's health,
Israel's government must decide whether to allow Palestinians living in
East Jerusalem to vote in Palestinian Authority elections scheduled for
25 January.
'Optimistic'
On Saturday, the director of the Hadassah Hospital said
a scan of Mr Sharon's brain had shown a slight reduction in swelling,
although the prime minister's condition remained critical but stable.
"First we have to stabilise the situation and fight for the life of the prime minister," Shlomo Mor-Yosef said.
"Then we will be able to evaluate the different neurological findings."
Mr Sharon's other vital signs, including blood pressure and pulse were within normal limits, the director added.
"We as human beings are optimistic. But I cannot say that the prime minister has come out of danger," he said.
'Low expectations'
Mr Sharon has undergone three rounds of surgery to stem bleeding in his brain from the stroke.

A brain scan following surgery on Friday showed the operation successfully released pressure on Mr Sharon's brain.
The BBC's James Reynolds in Jerusalem says there appears
to be little expectation in Israel that Mr Sharon will make a
meaningful recovery.
A general election is to go ahead as planned on 28
March. As head of the recently formed Kadima (Forward) party, Mr Sharon
had been widely expected to win re-election.
US Secretary of State Condoleezza Rice has cancelled a
week-long trip to Australia and Indonesia amid concerns about Mr
Sharon's health.

man and show a bit of humanity
