Dear Gurudev, if every formless is Shiva and every form is Shakti, then what is breath, which is both form and formless?
Yes, the formless is Shiva and the form is Shakti. You can define it in any manner.
Prana (life force energy obtained from breath) is also known as Mukhyaprana.
Hanuman is connected with prana, air (Vayu Tattva) is connected with prana, Omkar is connected with prana. So everything is prana in the universe. We are in an ocean of prana, and prana is both Shiva and Shakti.
A point comes where you cannot distinguish between Shiva and Shakti. The border vanishes, it becomes invisible. Shiva and Shakti become one. That is when it is called Brahman, which means it is all one; there is no second.
Advaita means, no second, no two (even to count to one, there must be two. That is why it is said, ‘There are no two things, just one’). It is one field of energy. Nothing other than that exists. Advaita means non-dual, it is the non-dual power in the universe.
This is the ultimate knowledge, i.e., non-dual, there are no two things. The whole universe is made up of one thing.
When you come one step below; it is like Quantum Physics. One more step below, and then it is like the Periodic Table in Chemistry. Do you know the Periodic Table? You have different elements, different aspects; these are all the different devas and devatas (specific divine energies).
