Učinkovitost in uporabnost katere koli metode za osebni in duhovni razvoj je seveda stvar subjektivne presoje in izkušenj.
No, izkušeni in s samo-realizacijami podkovani posamezniki o Kriyi pravijo:
Sri Babaji mi je dejal:
“Kriya yoga je za ljudi z levjim srcem.”
Swamy Parabhananda, ki je s to tehniko dosegel osvoboditev:
“Kriya yoga je najpreprostejša tehnika za doseganje popolnosti. Aspirant poleg nje ne potrebuje nič drugega, njegov napredek pa je popolnoma odvisen od lastnega napora.”
Sam Shiva, Sri Babaji tudi pravi:
“Pot Kriye (Kriya v Sanskritu pomeni akcija, delovanje) je najvišja. Nič se ne more primerjati s Kriyo. Pravzaprav, nič razen Kriye sploh ne obstaja. Združevanje katerihkoli dveh ali več stvari je Kriya yoga. Popolnost pri delu je prava Kriya yoga.”
Swamy Satyananda Saraswati iz Biharske šole yoge pravi:
“Kriya yoga je najučinkovitejša metoda za postopno dvigovanje človekove zavesti od vseh, ki so kdaj koli nastale. Nikoli se ni poučevala javno. Ta tehnika je premočna za nepripravljenega aspiranta.”
“The aftereffects of Kriya bring with them the utmost peace and bliss. The joy that comes with Kriya is greater than the joys of all pleasurable physical sensations put together.”
“The Kriya Yogi mentally directs his life energy to revolve, upward and downward, around the six spinal centers (medullary, cervical, dorsal, lumbar, sacral, and coccygeal plexuses) which correspond to the twelve astral signs of the zodiac, the symbolic Cosmic Man. One-half minute of revolution of energy around the sensitive spinal cord of man effects subtle progress in his evolution; that half-minute of Kriya equals one year of natural spiritual unfoldment.
The astral system of a human being, with six (twelve by polarity) inner constellations revolving around the sun of the omniscient spiritual eye, is interrelated with the physical sun and the twelve zodiacal signs. All men are thus affected by an inner and an outer universe. The ancient rishis discovered that man’s earthly and heavenly environment, in twelve-year cycles, push him forward on his natural path. The scriptures aver that man requires a million years of normal, diseaseless evolution to perfect his human brain sufficiently to express cosmic consciousness.
One thousand Kriya practiced in eight hours gives the yogi, in one day, the equivalent of one thousand years of natural evolution: 365,000 years of evolution in one year. In three years, a Kriya Yogi can thus accomplish by intelligent self-effort the same result which nature brings to pass in a million years. The Kriya short cut, of course, can be taken only by deeply developed yogis. With the guidance of a guru, such yogis have carefully prepared their bodies and brains to receive the power created by intensive practice.
The Kriya beginner employs his yogic exercise only fourteen to twenty-eight times, twice daily. A number of yogis achieve emancipation in six or twelve or twenty-four or forty-eight years. A yogi who dies before achieving full realization carries with him the good karma of his past Kriya effort; in his new life he is harmoniously propelled toward his Infinite Goal.”
