Yoga, in this path, is the effort to unite the small and restless mind with its own source. The spirit of it is not display. A posture held for applause, or a quiet face worn for a photograph, can leave the person exactly where they were.
The spirit shows up as sincerity. Come when the class is held. Learn from a qualified Acharya, in person, the practice that belongs to you. Do not collect techniques from a page and call the collection a path. Personal meditation and mantra are given by a teacher, not printed in a letter.
Between classes, the spirit is ordinary honesty. Eat in a way that leaves the mind clear. Speak in a way that does not scatter you. Offer some part of the day to someone else's need. Union that never touches conduct is only an idea.
This fortnight's invitation is modest. Sit with the practice you have been taught, for the time you can truly keep, and let one act of service follow it. The spirit of yoga is that sequence, repeated until it is simply how a day is made.
