morning ablution

Yoga practices specify that one should evacuate natural urges in the morning gazing toward the north, sitting in a proper private place, not gazing toward auspicious objects, …

One should tighten the abdominal muscles and do a brief muladhara contraction before release.  To aid this, ancient urinals were designed to have men bend on one knee to urinate. The closer we are to squatting, the more easy we will release fluids and solids from our bladder and bowels.
