Sadhanna- pronounced sod h na

what is the best time to do Kundalini Yoga

The early morning (4am to 7am - translating from the italian they are "the
hours of Ambrosia") is the best moment to pratice (in that moment the sun
light arrives on the earth with an angle of 60° so the prana can be
absorbed more easily*), but it's important (especially for the beginners)
to just find a moment during the day to pratice (without disturbs of any
kind).
