What is the meaning of 'Sham no Varuna' on the new insignia of Navy? And why was St. George's Cross removed?

The Red Cross has been removed from the New Ensign of the Indian Navy. There is a tricolour in the top left. On the other hand, Ashok Ensign is made in golden colour on a blue background, under which 'Satyamev Jayate' is written. The Ashoka symbol on it is actually the royal seal of Chhatrapati Shivaji Maharaj. In the new flag, 'Sham no Varunah' is written in Sanskrit language below.

How will the flag be different?

On 2 October 1934 The name of the service was changed to the Royal Indian Navy. And when the armies of India and Pakistan were formed after partition,the Indian Navywas divided into the Royal Indian Navy and the Royal Pakistan Navy. After this, on 26 January 1950, the word Royal was removed from and renamed. Before independence, the British flag resided in the upper corner of the naval flag. The tricolour was put in its place. According to the information received now, the mark of the cross will be removed in the new flag. The cross in the flag is the symbol of St. George.

What does the changes means

In the new flag of the Indian Navy, the tricolour of India's national flag has been placed in one corner. At the same time, a navy crest has been installed in the remaining half. This blue crest is in the shape of an octagon, which symbolises that the reach of our Indian Navy is in all eight directions. 

Apart from this, below the octagonal emblem, the Indian Navy's aphorism 'Sham no Varuna' has been inscribed in Devanagari script. The basic meaning of this sutra is that "May Varuna, the god of water, bless us." According to the Indian Sanatan tradition, Varun Dev is considered the god of water.
