Lower chakras

Something i have been trying to research, but the most i can find are brief descriptions. does anyone know how to open these chakras?

 Patala in the soles of the feet,
 Mahatala in the feet,
 Rasatala in the ankles,
 Talatala in the calves,
 Sutala in the knees,
 Vitala in the thighs,
 Atala in the hips.

I think I would benefit greatly from a theoretical waffle right now. With cream and cinnamon. Maybe some strawberries, too…
