Shiva’s trishul represents the three fundamental aspects of life. In the yogic tradition it is called Rudra, Hara and Sadashiva. These are the three fundamental dimensions of life that are symbolized in many ways. They can also be called Ida, Pingala and Sushumna. These are the three basic nadis – the left, the right and the central – in the pranamaya kosha, or the energy body of the human system. Nadis are pathways or channels of prana in the system. There are 72,000 nadis that spring from the three fundamental ones. These nadis don’t have a physical manifestation. If you cut the body and look in, you will not find them. But as you become more aware, you will notice the energy is not moving at random, it is moving in established pathways. There are 72,000 different ways in which the energy, or prana moves.
The Pingala and Ida represent the basic duality in the existence. It is this duality which we traditionally personify as Shiva and Shakti. You can simply call it masculine and feminine, or it can be the logical and the intuitive aspect of you. It is based on this that life is created. Without these two dualities, life wouldn’t exist as it does right now. In the beginning, everything is primordial, there is no duality. But once creation happens, there is duality.
When I say masculine and feminine, I am not talking in terms of sex – about being male or female – but in terms of certain qualities in nature. Certain qualities in nature have been identified as masculine. Certain other qualities have been identified as feminine. You may be a man, but if your Ida is more pronounced, the feminine may be dominant in you. You may be a woman, but if your Pingala is more pronounced, the masculine may be dominant in you.
Bringing a balance between the Ida and Pingala will make you effective in the world; this will allow you to handle life aspects well. Most people live and die in Ida and Pingala. Sushumna, the central space, remains dormant. But Sushumna is the most significant aspect of human physiology. Life really begins only when energies enter into Sushumna. You attain to a new kind of balance, an inner balance where whatever happens outside, there is a certain space within you that never gets disturbed and cannot be touched by outside situations. Only if you create this stable situation within yourself, you will dare to scale the peaks of consciousness.
