jana gana man adhinaayaka jay he

A query received  Regarding Gurudev Tagore's Jana gana mana adhinaayaaka jaya he
"Quote,, Jana Ghana mana,,, why tagore used the words adhee nayaka,,, what does it mean,,, was it a mistake, not debating , humbly curious to know the meaning,,"

My reaction on the issue.
"We need not be apologetic about that..
The poem was penned originally in praise of the ruler of that period..
But when the poem is adopted as the song of free India, all of us had the clear understanding that the same words being used to signify the Supreme being.. who is the adhi naayaka or supreme God who is the lord and controller of the minds of the large number of citizens of the country and who is to there to grant great fortune to Bharat.. and we are wishing victory to Him and in turn to our own Nation..
So the second context when we adopted it as the national anthem of India is very noble and everyone who chants that song thinks of the Supreme Divine being who grants fortune to Our Mother India and we never think of any British Monarch..
So where is the problem?..
In fact, the words of great visionaries, irrespective of being spelt out in different contexts, become prophetic..
And Gurudev was indeed a great visionary..
Adhi Naayaka, as we understand when we chant our National Anthem is the Supreme Being or our own Sovereignty personified.
