3 Brilliant Sutras devoted to Shree Mantra-Siddhanta:
"Shree ParashuRama Kalpa-Sutra", 1.7:
वर्णात्मकाः नित्याः शब्दाः । । ७ । ।
Eternal are the words constituted of letters.
The words constituted of letters are
eternal. The Mantras are not constructed by the humans and subject to dissolution as all human constructions are.
eternal. The Mantras are not constructed by the humans and subject to dissolution as all human constructions are.
They are formed out of the eternal Speech, the expressive stress of the Primordial Consciousness, and hence carry its supernal potency.
"Shree ParashuRama Kalpa-Sutra", 1.8:
मन्त्राणामचिन्त्यशक्तिता । । ८ । ।
The power of the Mantra is unthinkable.
Though the meaning of the Mantra is ascertainable by the mind and can be dwelt upon by the concentrated thought of the mind, its power is beyond the range of the mind to measure.
That is because the power is not derived from a mental origin.
It proceeds from a deeper and higher plane of existence from where the mind falls back.
"Shree ParashuRama Kalpa-Sutra", 1.32:
दीक्षास्तिस्त्रः शाक्ती शांभवी मान्त्री चेति । तत्र शाक्ती शक्तिप्रवेशनत्, शाम्भवी चरणविन्या-सात्, मान्त्री मन्त्रोपदिष्ट्या सर्वाश्च कुर्यात् । । ३२ । ।
Three initiations: shakti, sambhavi, mantri; of these,
shakti by the infusion of power;
sambhavi by placing the foot;
mantri by the communication of the mantra.
All should be performed. There are several kinds of initiation. Of these, however, 3 are the main: shakti, the initiation by sakti, power, is done by a direct transmission* of his spiritual power by the Guru into the being of the disciple;
sambhavi is effected by some physical contact like the placing of the charged foot by the Guru on the body of the disciple;
mantri is done when a chosen mantra is communicated by the Guru to the disciple; his spiritual dynamism is deposited in the disciple in the form of the mantra.
The wise Guru uses all these means, deciding in each case which is the most appropriate.
