In Sanskrit and many Indian languages milky ocean is known
as Ksheera Sagara.
The most famous incident associated with milky ocean is that
of the churning of ocean or Samudra Manthan by Asuras and Devas to attain
Amruta or elixir of life.
As per Vaishnavas, Vishnu sleeps blissfully on the milky
ocean before the creation of the universe.
Milky ocean is depicted on the walls of many temples and is
constantly mentioned in devotional poems and songs.
As per Swami Tejomayananda of Chinmaya Mission, the milky
ocean symbolizes our subtle body of the mind, intellect, ego and memory. The
churning must be done only in the subtle body. There may be various
interpretations, but it is only in the subtle body (mind) that the churning
must constantly take place. This churning the prelude to meditation.
As per one story, Surabhi, the divine cow, who resides in
the Rasa Tala, the seventh stratum below earth, shoots a single jet of her milk
in the universe and this creates the milky ocean. The verge of the ocean all
round is always covered with white foam resembling a belt of flowers. Those who
escape from the clutches of birth and death through self realization dwell
around the ocean subsisting on that the foam from the ocean.
