Many laws exist in physics, such as the principles of thermodynamics; gravity; Newton's, Coulomb's, Stefan's, Pascal's, and Hooke's Laws; Bernoulli's Principle, etc. There are so many laws in the universe that it is nearly impossible to articulate, categorize, or identify them all. The same with spiritual laws. The internal universe is profound, sophisticated, subtle, and incredibly vast. Even if we could name a number of these laws it would serve no practical purpose, because according to the scientific method, we must first form a hypothesis and test through experimentation.

Experiment with the teachings in yourself. Learn to meditate and awaken within the internal dimensions. In this way you naturally experience the laws of those dimensions and come to understand them, not through making an intellectual list, but through spiritual, direct, living facts.

Some laws of the astral plane are levitation, elasticity, plasticity: the abilities to fly, stretch the body, and move through walls. Many of the siddhis or psychic powers of the soul mentioned by Patanjali in his Yoga Sutras can be studied, since they relate with the ability to manipulate internal (and even physical) phenomena, The universe is composed of laws that are very remarkable and divine, and to try to list them in a "definitive" way would fail to capture the joyful reality of the spirit.

If you are interested in learning what the different dimensions are like, study the Tree of Life: the Kabbalah. That is the best map and guide for understanding our internal experiences. A number of the spiritual laws of the cosmos are articulated and symbolized by the different Sephiroth, "emanations," of this tree. Therefore, study this map and meditate on its relationship to your life for a true comprehension of the universe.
