History and origin
Kriya names both a precise inner practice and, in older hatha manuals, the cleansing acts. The six cleansings of those manuals are a different use of the word. They are not taught here. The meditation kriya associated with Lahiri Mahasaya, a Bengali householder of the nineteenth century, is a disciplined way of breath along the spine, given by a teacher, not copied from a page. This guide describes the path. It does not teach the technique.
The practice spread through several lines of householder teachers. One of them was later carried outside India by Paramahansa Yogananda and the organisation he founded. That organisation is a separate page. This page is the wider word: a breath taught in person, timed to the student, and not a studio posture series. Nothing below is an instruction in the initiated method.
Philosophy
Attention, in the way the line describes it, rides a steady breath through the subtle channel of the spine. That is the tradition's language, not a map this page will draw on a body. The point is not sensation for its own sake. It is a quiet, repeatable concentration that a living teacher times to the student. Improvising a current, a hold or a sound in order to feel something is a different activity, and it is not this practice.
How a class proceeds
In a public class you will sit, lengthen the spine, and work with simple breath. You may be asked to notice the inhale as a lift along the back and the exhale as a settling, without strain in the throat. The specific kriya, if it is offered at all, comes only after instruction from a teacher in that line. Nothing here should be forced or improvised as if it were the initiated practice.
The hour is quiet. There is no long sequence of standing poses and no music to cover the silence. A teacher who knows the method will not print it on a sheet for you to take home. If a class offers the full technique to strangers on a first evening, that is a reason to be cautious, not a bargain. You can learn to sit well without pretending you have received what you have not.
Intensity
The physical load in a public hour is moderate only because sitting upright for a while is real work. There is no sweat to chase and no pose to conquer. The concentration can be tiring. The throat, the jaw and the eyes should stay soft. If you feel strain behind the eyes or a forced breath, you have left the simple preparation and should stop. The initiated practice, when a teacher gives it, has its own measure. That measure is not printed here.
Benefits
A person who sits daily, with an ordinary breath and a long spine, often finds it easier to notice distraction without chasing it. The shoulders, if they are allowed to drop, complain less at a desk. Those are modest and practical effects of the preparation. They are not the fruit the line speaks of, and this page will not name a fruit it refuses to teach. Waiting for a teacher is part of the method, not a delay in front of it.
Who it suits
People who want a meditation of breath and spine, and who will wait for a teacher. It suits those who can sit, who are not in a hurry to feel a special current, and who understand that a public hour is only the outer shape.
A poor fit if you want a fitness sequence or a technique you can invent alone. It is also the wrong page if you came for the six hatha cleansings, for a rhythmic group breath taught as a course, or for the initiation class of one particular organisation. Those are other practices. They share a word. They do not share this method.
Beside similar forms
This kriya is the breath associated with Lahiri Mahasaya. It is not the six cleansing acts of the hatha manuals, though those acts are also called kriyas. It is not the repeated exercises of a studio kundalini class, and it is not a rhythmic course-breath taught to a large group in a weekend. Self-Realization Fellowship carries one line of this family after a formal initiation, together with its own energization exercises. That is an organisation. This page does not teach its initiation, and it does not reduce the wider path to that one school. Raja yoga is Patanjali's eight limbs. A public kriya hour may look like quiet sitting. The technique, if it comes, comes from a person.
Best positions
Tall seat
Sit on a cushion or a chair so the spine is long and the jaw is soft. Let the shoulders drop and the hands rest on the thighs. The breath stays quiet and uncounted. The seat is the public shape of the path: a back that can stay upright without bracing. It prepares attention. It is not the technique.
Spine breath
Feel the inhale as a lift along the back and the exhale as a settling. Do not strain the throat, do not hold the breath, and do not aim the air at a point you have read about. This is ordinary observation in a public hour. It steadies the trunk and teaches the ribs to move. It is not the initiated breath, and it should not be decorated until it resembles one.
Still close
End seated, hands quiet, eyes soft, and leave the practice without reviewing it for a result. Sit until the next breath is ordinary. The close keeps a simple hour from being turned into a story about progress. It also keeps you from adding, in the last minute, a method you were not given.
Shoulder ease
Sit tall and roll the shoulders slowly up, back and down, three times, then leave them dropped. Do not pinch the blades together. The movement is only to show the shoulders that they need not hold the sitting. A quieter shoulder lets the neck stay long, which is the whole use of the shape.
Hands on knees
Rest the palms on the knees, fingers relaxed, elbows slightly bent so the shoulders can hang. Do not press down to force the spine straight. The hands are a weight that reminds the arms to stop helping. The pose makes an upright sit less brittle, and it gives the eyes less reason to wander toward a task.
Counted rest
Count six ordinary breaths, then stop counting. Do not lengthen them to match a number you have seen in a book, and do not call the count a kriya. The short count settles a restless start. Stopping is the point: a preparation that knows it is a preparation, and then gets out of the way.
Lying quiet
Lie on the back for a few minutes with the knees bent if the low back complains, arms away from the sides. Do not search the spine for a current. The lie lets the sitting muscles stop working and shows you the difference between effort and rest. Stand up before you drift into sleep if you still need to travel home.
