(1) Walk with head up, chin drawn slightly in, shoulders back, and
with measured tread. (2) Inhale a complete breath, counting (mentally)
1, 2, 3, 4, 5, 6, 7, 8, one count to each step making the inhalation
extend over the eight counts. (3) Exhale slowly through the nostrils,
counting as before 1, 2, 3, 4, 5, 6, 7, 8, one count to a step. (4) Rest
between breaths, continuing, walking and counting 1, 2, 3, 4, 5, 6, 7, 8,
one count to a step. (5) Repeat until you begin to feel tired. Then rest
for a while and resume at pleasure. Repeat several times a day. You may
vary the exercise by retaining the breath during a 1, 2, 3, 4, count and
then exhale in an eight-step count. Practise whichever plan seems most
agreeable to you.
