God is one, but the religions are many. The people of all religions, want to realize God by the five sense organs, but God has given these sense organs only for their restlessness. There are fifty types of breath of which there are forty-nine types for restlessness and one short breath, the finest breath, a faint breath, the one that goes straight to the fontanel when you inhale. With this faint, shortest breath, you can not get anger, pride, cruelty, sex or any other restlessness.
It is said in the Hatha Yoga Pradipika 4: 114, yavat naiva pravishati charan maruta madhya marge-the breath must be very feeble, faint and going straight to the fontanel, where the baby has the softest place on the top of the head. You are to watch very carefully in that place. Then you will feel pulsation. Then you will hear divine sound. Then you will see divine light and you will also get love for God.
God made man and woman in His own image and He breathed into these bodies the breath of His life and He became the soul of the whole universe. So, the supreme almighty Lord remains in every human body. Every human body is the body of the supreme almighty Lord and He has given His love to this body. If you take the shortest breath, you will get calmness, which is godliness, but instead most people are teaching about God by reading books or by singing songs or by dancing, or by rotating or many, many other ways. Although I do not like it, I am not going to criticize anybody.
Suppose, that you all are students going to school, listening to the teachers and after that you go home and prepare your lessons very nicely. Then you will come out successfully. Here people are going to the church but only on Sunday (not seven days a week), the priest will read for only one hour and they expect to get God-realization? That is impossible. You take food daily, regularly and sincerely.
This is why your body is increasing. And through that you are getting everything. Similarly, you should keep your attention on the top of your head and take a very little breath, search Him inside the head and then you will see milk white light, covering the whole body with the divine light.
Calmly search God in the fontanel, surely you will get God-realization. Practice Kriya well.
It is said in the same Hatha Yoga Pradipika 4: 114, if the breath is not very feeble you can not get God-realization: yavat dhyana sahaja sadrisham jayate naiva tattwam — if the meditation technique is not the easiest and simplest, then you can not get God. He is taking breath and you are watching. This is the simplest technique. Everyone, people of all religions, are breathing. It is why they all are alive. Breath is our life. So you all should watch and see calmly with the short breath whether you are feeling pulsation on the top of your head and by the side of the ear, above the ear; whether you are hearing sound, constant sound. If you only practice this and see constant light all over the world then automatically you will get samadhi stage, pulselessness stage, breathlessness stage. You will get reality, truth. It is possible.
Kriya Yoga is a very specific system of Yoga that was revived in modern times by Lahiri Mahasaya, c 1861 Paramahansa Yogananda brought it into widespread public awareness through his book Autobiography of a Yogi. The system consists of a number of yogic techniques that hasten the practitioner's spiritual development and help to bring about a profound state of tranquility and God-communion.
Yogananda writes that, "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 mystic and liberating Yoga technique was almost extinct in the medieval period, when the world was under the influence of religious fanatics and nobody was mature enough to accept the truth. Even Galileo was prosecuted for stating the truth as it was. Later when the time changed and became somewhat more favorable for discussing the truths of life and nature, the general consciousness of mankind begin to develop and there was a general awakening for realizing the hidden and invisible facts of life which science began to discover, then, in 1868, the great Yogi guru, whom we know by the name "Babaji", again introduced this mystic Yogic art to the society through his disciple Shyamacharan Lahiri. Babaji is ever the same. He was never born and therefore can never die. They call him aja (the unborn). But from time to time this compassionate Lord of irradiant splendor does manifest for humanity to do what needs to be done. Pulling the veil of Maya by his own will he takes a form of Lightless light to incarnate amongst the haunts of men. He guards, guides and enlightens their consciousness as per their evolutionary blueprint. His deathless body of lightless light may take any form through which he can express and show himself to the faithful from age to age. He took the form of Adi Nath Shiva himself of Rudra of the Ancient of days. He then came 500 B.C. as Kal Agni Nath as Dakshin Murti when he initiated himself then he manifest as Gorksha Nath 70 B.C at the time of King Shalivahan and Chowrangee Nath.Then in the same ever present immortal body he manifests as Shiv Goraksha Babaji in the ninth centrury A.D. during the time of Guga Nath who he empowered to have complete mastery over the Nagas and ultimately be worshipped as a Naga God.
The day Babaji initiated Shyamacharan Lahiri and sent him back to the society, from that very day all true seekers of truth found the means to realize the truth of life and death and beyond. Shyamacharan Lahiri demonstrated most of the results of this mystic Yogic art by putting his own example. All his life, he indicated the Yogic way to true seekers and introduced them to the different stages of this mystic Yogic art. After his demise, some lines of his disciples have maintained the practice of this mystic Yogic art.
Among the famous traditions, the tradition of Shri Yukteshwar Giri, disciple of Lahiri Mahasaya, became world famous through his able disciple Paramhans Yogananda. Paramhans Yogananda graced the Father of Indian Nation — Mahatma Gandhi with Kriya yoga diksha, who initiated the entire human race onto the path of non-violence in the blood-soaked century.
