Patanjali’s  Definition of Yoga



  Now instruction in yoga.

  Yoga is the restraint of fluctuations of the mind.

  Then there is abiding in the seer's own fundamental nature.

  Ignorance is the origin of the others, whether dormant, attenuated, interrupted, or fully active.

  At other times it takes the form of the fluctuations.

  Valid cognition, error, conceptualization, sleep, and memory.

  Valid cognitions are perception, inference, and valid testimony.

  Error is false knowledge, without foundation.

  Conceptualization is the result of words and ideas empty of object.

  The sleep fluctuation is based on the intention of nonbecoming.

  Memory is the recollection of an experienced condition.

  Through practice and dispassion arises restraint.

  Effort in remaining there is practice.

  But that is firmlt situated when carefully attended to for a long time without interuption.

  Dispassion is the knowledge of mastery in one who thirsts not for conditions seen or heard.

  That highest (dispassion) - thirstlessness for the gunas - [proceeds] from the discernment of purusa.

  Samprajnata [arises] from association with discursive thought, reflection, bliss, and I-am-ness.

  The other (state) has samskara only and is proceded by practice and the intention of cessation.

  Of the one who are absorbed in prakriti and discarnate, [there is] an intention of becoming.

  Of the others it is proceded by faith, energy, mindfulness, samadhi, and wisdom.

  The strongly intense ones are near.

  Hence the distinctions of mild, moderate, and ardent.

  Or from dedication to Isvara.

  Isvara is a distinct purusa untouched by afflictions, actions, fruitions, or their residue.

   There the seed of omnisccience is unsurpassed.

  Due to its being unlimited by time, it is the teacher of the prior ones.

  Its expression is pranava (OM).
