Let me see if I can remember that day's flow. A nice challenge for the memory banks. Usually I can only do that flow when we have less than 20 people in the room (which means only on Oscar Sundays), due to limited wall space. Let me first list the postures, then I will describe some of the variations:
Sitting meditation ---- arriving and centering
Against the wall...snuggling your butt to the corner of the wall and floor
Butterfly .... let your heels come as low as they can, allow the knees to go as wide as they can.
Legs straight up the wall (ie: Caterpillar)
Squat: placing both feet against the wall, wider than the hips.
Wide-angle legs (ie: Straddle) ... let the legs fall apart as far as they can go
Eye of the needle:right side
Reclining twist: left side
Eye of the needle: left side
Reclining twist: right side
Sphinx with knees bent, and shins up against the wall
I think that was the full flow. We held the poses for about 6 minutes each but, of course, that is variable.
The wall squat (my favourite) is easily reached from Caterpillar...simply slide the feet down the walls, keeping them at hip width apart, or wider if possible, until the sacrum starts to lift off the floor. Either stay with the feet at that height, lowering them little by little as the body opens up, or slide the butt away from the wall until the sacrum can stay flat.
The eye of the needle poses need some description for getting into/out of them. Start with the legs straight up the wall, then place the right ankle just below the left knee flexing the foot strongly to protect the knee (since you are upside down "below" means closer to the floor, which actually is above the knee, if you were standing, ie: on your thigh.) Now bend the left leg by sliding the left foot down the wall, until you get a nice stretch in the right hip. For many people, the sacrum will again rise up, as with the squat. This can be okay: you may want to stay there and let your hips be off the floor, or you may choose to move a bit away from the wall until your sacrum is again flat on the floor. One is not better than the other position: just different. Notice the differences in where you feel each variation, then choose which one you want to do today.
From the eye of the needle we come into a reclining twist by simply lowering the lower body (the legs and hips) to the floor while keeping the upper body where it is. You may want to spread your arms wide apart to help anchor your shoulders, then drop your right foot and left knee to the left and find a comfortable twist. Having your left foot still touching the wall will keep your knees closer to your chest, which can make this a deeper twist for many students.
The order was done for specific reasons, but feel free to experiment with your own arrangements. We didn't have the space to do another pose that I really like doing at home...it is a variation of the reclining twist against the wall. If you have room you may want to try this too: lying so the wall is to your right and parallel to you, and just a couple of feet away, draw your left leg into the chest; use your right hand to hold the knee in, opening your left arm to the left for anchoring; draw the left leg across the body and roll onto your right hip, keeping both shoulders on or close to the floor; now ... try to straighten the left leg and rest the foot against the wall. As you open up with time, slide your torso closer to the wall. Hopefully you can picture what I mean. Don't forget to do both sides.
Hope this helps.
