A vast reconstruction of the knowledge of the ancient Jewish priest-scientists, with vital implications for contemporary spirituality and science. - Reveals an ancient science that used geometry, sound, and number to link the finite world of human experience with the infinite realm of the divine. - Uses teachings extending back thousands of years to explicate key concepts of quantum physics and quantum cosmology. For centuries the Kabbalah has fascinated devotees of mysticism while its origins have remained obscure. Now, in her brilliant new work, Leonora Leet reveals that the Kabbalah was the product of a sophisticated, though largely forgotten, Hebraic sacred science that was the rival of any in Egypt or Greece. Not only does Leet reconstruct the secret teachings of the priest-scientists of the Hebrew temple, she also shows them to be the key to understanding both biblical and kabbalistic cosmology. Unlike previous purely historical explorations of the Jewish esoteric tradition, The Secret Doctrine of the Kabbalah resurrects this ancient body of knowledge to reveal eternal truths that can have a profound and positive impact on contemporary spirituality. New experimental methods of practicing Hebraic sacred science are explored that explain as never before the meaning of the central cosmological diagram of the entire Western esoteric tradition--the kabbalistic Tree of Life. Leet shows that the Kabbalah and its central diagram enshrine a key to the purpose of the cosmos, a key that has vast implications for modern physics and cosmology. In a final synthesis, she envisions a culmination in which the universe and its divine child, perfected humanity, achieve that unification of the finite and infinite which has ever been the secret doctrine of the Kabbalah.Binding Type: Paperback

Worth its weight in gold
Color: Ocean Blue, Style: Everyday 3 Season 50-80° F
Great, left the wind & cold out. Kept me warm with 17* wind chill! Durable. Couldn’t have asked for better warmth made sitting @ watching a soccer game doable. It’s literally lite weight, has a convenient of a carrying bag.

Great sleeping bag
Color: Ocean Blue, Style: Everyday 3 Season 50-80° F
Great size for my 10 year old son. Nice and long. The material is soft and warm. The zipper zips fast. There is like a hoodie on the top to go over your head to keep you warm.

Great for school trips and camping
Color: Sunburst Orange, Style: Everyday 3 Season 50-80° F, Color: Sunburst Orange, Style: Everyday 3 Season 50-80° F
My daughter went on a school camp trip and needed a sleeping bag, so I decided to get this one. I chose the adult size instead of the kids’ version so we can use it in the future too. It turned out to be a great choice — it’s roomy and comfortable, and even I fit inside easily.
The material feels soft and pleasant to the touch, and the zipper works smoothly without getting stuck. It keeps you warm at night but doesn’t feel too hot, which is perfect for cool-weather camping. I did notice that along the edges there’s a section without insulation for quite a bit of distance — not a big issue, but something to be aware of. I tried to show this part in my video.
The color is bright and cheerful, exactly as shown in the pictures. Overall, I’m very happy with this purchase — it’s lightweight, cozy, and easy to use. The only challenge is rolling it up and fitting it back into the carrying bag. Even for me, it took some effort since the sleeping bag is quite bulky. The material seems sturdy and well-made, but we’ve only used it once, so time will tell about its durability. Maybe the manufacturer could improve that part in the future. Still, it’s a great option for school trips, camping, and sleepovers.

Warm, comfortable, and great value for the price
Color: Ocean Blue, Style: Everyday 3 Season 50-80° F
I bought this sleeping bag for my son on a recent camping trip, and it performed surprisingly well. It warms up quickly once you’re inside, and the material feels soft and comfortable against the skin. The zipper runs smoothly and doesn’t get stuck easily, which is a big plus.
It’s lightweight and packs down small, so it’s easy to carry and doesn’t take much space in his backpack.
However, It’s not warm enough for very cold nights below the temperature rating, so if you’re camping in winter, you may need an extra blanket or liner.
Overall, for the price, this sleeping bag is an excellent buy—comfortable, warm, and very practical. I would like to give five stars.
