All day long they come to a simple bungalow in a small garden in this tiny village to pay homage to the man who is out to end, the long reign of Shah Mohammed Reza Pahlvai of Iran.

For the most part, they are young Iranian students - men and a sprinkling of women - who have made the pilgrimage from all over Western Europe to see and listen to Ayatollah Rubollah Khomeini.

The Routine has barely changed in the 10 days since Khomeini, the Shite Moslem leader whom the shah exiled in 1963, was expelled from Iraq and sought temporary refuge in France.

Morning and evening, Khomeini appears from the Bungalow's second floor, his white-bearded head topped with a black turban, a brown collarless coat over a collarless green tunic, his feet clad in blue plastic sandals.

The waiting crowd of more than 50 Iranians - the women's heads covered by scarves - is openly exhilarated by the chance to see Khomeini.

A chemical engineering student from Britain sums up the mood, saying: "He is our political and religious leader and we are honored to have the chance to see the ayatollah."

But the students are afraid to give their names.

"SAVAK," the shah's secret police, is still very active and very dreaded," one young woman says.

As his admirers chant," "Allah is great and peace be with his prophet and descendants," the spry 78-year-old ayatollah walks down the concrete steps and sits cross-legged on a Persian carpet under heavily laden apple trees.

He leans against a pillow placed against a stout apple tree.

The admirers kneel on blankets and carpets and strain forward to hear the low-pitched voice explain yet another time the reasons for his long struggle. A half dozen tape recorders capture his words for history.

The themes do not vary: The PPahlavi dynasty must go. No compromise is possible. The army must rise up and help overthrow the shah."

Constantly repeated since January, when violence first erupted between the Shiites and the police, these themes have shakey one of the Third World's once most outwardly secure governments.

Outside the garden and its Roses, French security police check comings and goings on an Indian summer afternoon.

In Paris about 25 miles to the east authorities ponder what to do about Khomeini, an embarrassment for the government that has billions of dollars in contracts tied up with the Shah.

As a compromise between their desire to keep Khomeini's campaign going and France's delicate position, his followers suggest Khomeini make no public declarations here, but that they be allowed to relay statements from him to Iran over the direct dial telephone system. Their idea is getting nowhere with the cautious French.

Theoretically, the ayatollah is a tourist and needed no visa to enter France. His supporters keep pointing out to French authorities that perhaps they should be more flexible since there is no telling whether the shah will be in power in a few months.

"They should think of the future and of their interests," one mane said, recalling that an Iraqi consulate in Iran was attacked after Baghdad forced Khomeini to leave the holy city of Najjaf and then quit Iraq entirely.

Khomeini's advisers have made it clear that he will not leave France without telling the world that the French government asked him to go.

"No hypocrisy," said one close confident.

But even Khomeini's advisers expect him to move on to several other European countries before he is likely to settle in Moslem land. Syria often is mentioned.

French officials forbade Khomeini from addressing an audience of faithful in Paris yesterday, according to his supporters, and now he is pondering what to tell Iranians to do later this week when the 40-day period of mourning for those killed in early September in Tehran is to be commemorated.

Fearful that more violence will only prompt the shah to name a military government, Khomeini is said to be thinking of asking the faithful to stay indoors rather than violate the martial law ban on all demonstrations.

All such plans are discussed in a ttiny brick - and - plaster house that is a far cry from Tehran or the golden domes of the Naffaf holy places.

The house, which belongs to an Iranian married to a Frenchwoman, was chosen in preference to the small Paris apartment where Khomeini first stayed when he was expelled from Iraq and turned back by Kuwait.

The French neighbors in this little village are divided about the hustle and bustle.

Sabine Thomas, 12 says, "We know he is for religion and against the shah."

But if school children bicycling by enjoy the spectacle, two old women who passed by recently seemed less amused.

"The butcher's wife is really mad about having to show her identity papers to the police all the time," one said.
