Bernadette Roberts stressed the Father's stillness when she called him “the 'still-point' at the center of being.” (35) Lao Tzu emphasized it when he asserted that: “The Way [the Tao or the Father] is a Void.” (36)
Empty of name and form, qualities and attributes, and quintessentially tranquil and still, the Father is in the end inconceivable. “What Brahman is cannot be described,” declared the Godman of Dakshineswar. (37) Because ego is subdued for a time upon attaining the Father, leaving no observer to observe, no thinker to think, “no one has ever been able to say what Brahman is.” (38)
The essence of the Mother is a universal creative vibration, symbolized by the sacred syllable 'Aum,' which calls matter into being, sustains it for a while, and then releases it back into the general dissolution of the Father
Hindus symbolize the primal power - the Mother as vibration or energy - by the sacred syllable – or rather vibration - 'Aum.' Sri Ramakrishna makes this connection when he equates Aum with the Divine Mother, exclaiming: “O Mother! O Embodiment of ‘Om.’” (39)
Paramahansa Yogananda identifies “Aum,” or “Amen,” with the Holy Spirit: Christians are familiar with the Amen from Revelation: “These things saith the Amen [the Mother], the faithful and true witness, the beginning of the creation of God.” (40)
The ancients, not versed in the polished language of modern times, used “Holy Ghost” and “Word” for Intelligent Cosmic Vibration, which is the first materialization of God the Father in matter [i.e., the Mother]. The Hindus speak of this Holy Ghost as the “Aum.” (41)
Holy Ghost, Aum of the Hindus, the Mohammedan Amin, the Christian Amen, Voice of Many Waters, Word, are the same thing. (42)
Yogananda links “Aum” and the “Holy Ghost” to the primordial energy:
“The Bible refers to Aum as the Holy Ghost or invisible life force that divinely upholds creation. ‘What? Know ye not that your body is the temple of the Holy Ghost which is in you, which we have of God, and ye are not your own?' (I Corinthians 6:19.)” (43)
Now we know the Mother, Shakti, the Holy Ghost, as Aum. Aum creates, preserves and destroys.
The cosmic sound of Aum creates all things as Nebulae, preserves them in the forms of the present cosmos and worlds, and ultimately will dissolve all things in the bosom-sea of God. (44)
This first perfect ray of Light is the Holy Spirit or Divine Mother. Its expansion in all directions is the birth of the universe. What we may be hearing is a vision of the creation of the universe -- what scientists call "the Big Bang."
This Light, this vibration called "Aum," the Divine Mother, is one with the vibrationless Father. Patanjali states: “The Word which expresses [God] is “Om“ (49) “Oh, Lord, dweller within,” says Shankara, “ “Om is your very self.” (50) Or the Upanishads: “Om is Brahman, both the conditioned [Mother] and the unconditioned [Father], the personal [Mother] and the impersonal [Father].” (51)
Three Hindu masters – Swami Yukestwar Giri, Swami Sivananda, and Paramahansa Ramakrishna explain the relationship between Brahman and Shakti, or Father and Mother, by using a fire metaphor.
Swami Yukteswar Giri, guru to Paramahansa Yogananda
[The] manifestation of the Word (becoming flesh, the external material) created this visible world. So the Word, Amen, Aum [the Mother], being the manifestation of the Eternal Nature of the Almighty Father or His own Self, is inseparable from and nothing but God Himself; as the burning power is inseparable from and nothing but the fire itself. (53)
Just as one cannot separate heat from fire, so also one cannot separate Sakti [Mother] from Sakta [Father]. Sakti and Sakta are one. They are inseparable. (54)
Brahman and Sakti are identical. If you accept the one, you must accept the other. It is like fire and its power to burn. If you see the fire, you must recognize its power to burn also. ... One cannot think of the Absolute without the Relative, or the Relative without the Absolute. (55)
“Sakti is Brahman itself,” concludes Swami Sivananda. (56) Sri Ramaskrishna agrees: “Brahman is Sakti; Sakti is Brahman. They are not two.” (57) “[Brahman and Sakti] are only two aspects, male and female, of the same Reality, Existence-Knowledge-Bliss-Absolute.” (58)
When we speak to the Divine Mother, we are speaking to the Holy Father. Sri Ramakrishna teaches: “It is Brahman whom I address as Sakti or Kali.” (59)
