Sutra 1.22

मृदुमध्याधिमात्रत्वात् ततोऽपि विशेषः ॥२२॥
mridu-madhya-adhimaatrat-vaat tato-api vishesha-ha ॥२२॥

Swami Satchidananda: “The time necessary for success further depends on whether the practice is mild, medium or intense.” So for those who practice with ardent intent and practice constantly the realization of the goal is near. There are many levels of 'being', and practice refers to the meditative state rather than a yoga workout.
