The Mother herself has translated it as follows.
OM β She, the Delight
She, the Consciousness
She, the Truth
She, the Supreme
(Ref. https://incarnateword.in/cwm/20/general-1)
It is the highest mantra of invocation of the Divine Mother revealed so far. It combines the three aspects of the Supreme Divine, Sacchidananda, as Truth, Consciousness, Bliss.
Affectionately,
Alok Da
