The ideas that came to me were:

Tantric visualizations of light-beings drawing amrita through their "vajra tongues" (flat vajras with a hollow central tube through which the essence of offerings is drawn in and consumed by the deity)

People snorting coke.

Actually, they appear to be consuming an iced refreshment through huge straws.

Whatever they're doing, it's a strange commingling of joint consumption and individual indulgence. Obviously it's a case of whoever sucks hardest gets most. Maybe that's supposed to be the game -- a little competition to get the greed going, in case appetites have started to flag from overindulgence.

I noticed that the people have their drinks on a rail below the bar. Tara says to look in the alley between the people, which gets strewn with garbage and raked out by the slaves, who are seen in the background.

Working on a Fellini movie must be the biggest party imaginable. The number of creatives you would have to stuff into one space to pull it off, all the makeup artists and script girls and prop movers and costume and wardrobe and location people, every task exploded bigger because of the ambition of the director's vision. Fellini ornaments each character in a baroque style, revealing the uniqueness of each human form, ruling nothing out, least of all what might in any other setting be thought grotesque. Fellini territory is the blossoming jungle of our hearts where we are once again wonderstruck children, willful adults, and exhausted ancients, participating voluntarily or otherwise in the carnival of life. Isaac Bashevis Singer said something like, "People say that God is a terrible author. His story is too long. It never comes to a point. But nobody ever stops reading!"
