EQUALITY AND DUALITY ARE THEMES IN HINDU MANTRA:

ॐ पूर्णमदः पूर्णमिदं पूर्णात्पुर्णमुदच्यते
पूर्णश्य पूर्णमादाय पूर्णमेवावशिष्यते ॥
“ Om purnam adah purnam idam
purnat purnam udachyate
purnasya purnam adaya
purnam evavashishyate”.

An ideological and free translation of the mantra begins with the word Om (ॐ), which is personified here as God. The term ‘Purnam’ and its related derivates in the mantra mean complete and signify His completeness.

He is Complete; everything emanating from Him is complete. From the Complete Wholeness, only the entirety manifests. And even when a single complete comes out from the whole Complete, what is left is still a Complete. The products produced through Him may look small or big, but in core and quality, all are complete units.

The mantra assures complete balance in all of His universal creations from the elements of nature to humankind. For humanity, the mantra conveys a message that every human being is equal in his or her completeness as manifested by Him.

Atma or a single soul is a complete manifestation of the Supreme-Atma. This duality of the Atma-Parmatma is called the Cause and effect association. Supreme-Atma is the Cause or the reason to produce an effect, meaning Atma.

The result cannot be less than the Cause. The Cause changes to the consequence, but continues to remain Cause also. In essence, the mantra reinforces that in every living being, there dwells the Supreme Atma as well.
Equality and divinity are the themes of the mantra concerning humanity.
