History and origin
Jnana is the yoga of knowledge in the Upanishads and the Gita. It asks what is lasting and what is only passing. The early texts do the work as dialogue: a student hears a passage with a teacher and stays with the question after the words stop. Study, dialogue and silence grew up together as one path.
Later Vedanta, especially the discipline associated with Shankara, set the work out as hearing, reflection and long contemplation. The method is not a pile of opinions. It is a repeated discrimination between the witness and the weather of the mind. A modern hour may be a short reading and a long sit. It is still that inquiry, not a lecture course and not a fitness class.
Philosophy
The practice is discrimination: seeing the difference between the witness and the weather of the mind. Neti neti — not this, not this — is a way of putting down false names. A thought, a mood, a role and a sensation are noticed as things that change. The texts make claims about what does not change. This guide does not treat those claims as facts you must accept. It describes the inquiry: read carefully, test the sentence, and do not hurry to a slogan.
How a class proceeds
Little choreography. You sit, read a short passage, and stay with one question. The body is arranged so the inquiry can be quiet. A teacher may read from an Upanishad or from the Gita and then leave a silence. You are not asked to agree on cue, and you are not quizzed for a correct face.
Between the reading and the silence there may be a few plain poses, only so the back can stay long. A notebook is sometimes used, so the mind cannot hide in a vague feeling. At the end you lie down or remain seated and let the question rest without solving it.
Intensity
The physical load is gentle. Sitting is the main demand, and a stiff hip can be helped with a cushion or a chair. There is no heat to pursue. The effort is mental: staying with one question without decorating it. People who dislike stillness will find the hour long. People who are tired in the body can usually still sit and listen.
Benefits
The practice trains a cleaner use of words. People often notice that they name a mood less quickly, and that a passing thought is less easily mistaken for a fact. An upright seat, held without strain, is a practical support for reading and for quiet. Nothing here is a treatment for illness. The old language of liberation belongs to the texts. This page does not promise it.
Who it suits
People who like clear thinking and silence. It suits readers who will sit after the paragraph ends, and who can bear a question that does not close neatly.
A poor fit if you want a fitness class. It will also frustrate you if you want a teacher to hand over a finished picture of the world. The method needs patience with not knowing. If silence brings up distress you cannot stay with, choose a room with more structure and a person you can speak to. Inquiry is not a substitute for care.
Beside similar forms
Jnana is inquiry. Raja yoga, in the Yoga Sutra, is the eight-limbed training of attention, from ethics to a mind that can stay, and asana is only one limb. They can share a quiet seat. Raja gives a graded practice. Jnana gives a discipline of seeing and of reading. Karma yoga keeps the question inside the work of the day. Bhakti trusts a name more than an argument. Hatha steadies the body so attention has a place to sit. A jnana hour may use a pose. The pose is not the path.
Best positions
Steady seat
Sit on a cushion, a bench or a chair so the spine is long and the knees are not forced. Let the hands rest on the thighs. Soften the jaw and leave the breath ordinary. The seat is there so attention can turn inward without a fight against the furniture. If the back tires, raise the pelvis rather than collapsing.
Listening pose
Use a simple cross-legged seat, or a chair, while a text is read aloud. Keep the eyes soft or lowered, and do not take notes yet. The pose lets the passage arrive before you answer it. Listening first keeps the inquiry from becoming a debate with the reader.
Open rest
Lie down at the end with the arms away from the sides and the palms turned up. Let the question rest without solving it. Do not turn the lie into a nap on purpose, and do not scan the hour for a conclusion. The rest gives the nervous system a quiet interval after close reading, and it stops the mind from grabbing a slogan on the way out.
Upright reading
Sit at a table with the book at a height that does not round the neck. Read one short passage twice, slowly, then stop. The upright seat keeps the breath free while the eyes work. Stopping after a few lines is the method: depth, not the number of pages.
Hands at rest
Sit and place the hands palms down on the thighs, fingers quiet. Do not fidget with a pen or a phone. For a few minutes, notice the next thought as an event, then return to the feeling of the hands. The stillness of the hands makes the mind's movement easier to see, which is the discrimination the path asks for.
Walking question
Walk slowly indoors or on a quiet path, with one question only, such as what in this moment is changing. Do not add a second question, and do not walk so fast that the breath becomes a project. The walk keeps inquiry from freezing into a rigid seat, and it shows the same discrimination while the body is in ordinary motion.
Silent close
Remain seated for a short time after the reading, eyes lowered, hands still. Do not summarise the hour out loud. Let one sentence you actually understood stay, and let the rest be unfinished. The close protects the inquiry from being turned into a conclusion you can show someone.
