I wrote a Blog Post with the title “How Many Universes Make A Multiverse – The Story of Bhetala” inspired by a story narrated by Sage Vasishta in the first part of the Sixth Chapter: Nirvana in Yogavasishta. The Link to the Post dated Nov 4, 2009 is here. The metaphor described was as follows:
“Think of the universe that we are all living in to be a humongous fruit.
There is a bough with thousands of those fruits.
There is a tree with thousands of such boughs.
There is a wood with thousands of such trees.
There is a mountain with thousands of such woods.
There is an island with thousands of such mountains.
There is a huge globe (mahi peetha) with thousands of such islands.
There is a huge star system with thousands of such globes.
There is a heavenly egg with thousands of such star systems.
There is a sea with thousands of such heavenly eggs.
There is an ocean with thousands of such seas.
Thousands of such oceans will be the waters in the stomach of a man.
That man’s name is Vishnu.
Another great man wears a necklace of a hundred thousand of Vishnus.
His name is Rudra.
Millions of Rudras shine in the form of hair-follicles on the body of a very great man. His name is Aditya (= one who has been there right from the beginning; sun).
He is none other than the Supreme Consciousness.
He illuminates all the universes of my gargantuan conception.
He is the Brahman with attributes.
He has also an absolute form that is much more fundamental.
The qualities of ‘doership’ and ‘experiencership’ which seem to exist in the Brahman with attributes do not at all affect the Absolute Brahman.
The star you are referring to is the Brahman with attributes.”
The Scientists of the University of Hawaii published the most detailed map of the Universe in Sept 2014.
“The supercluster of galaxies that includes the Milky Way is 100 times bigger in volume and mass than previously thought, a team of astronomers says. They have mapped the enormous region and given it the name Laniakea — Hawaiian for ‘immeasurable heaven’.”
