Non-Dual Shaivism, also known as Kashmir Shaivism, is a philosophical and spiritual tradition that emerged in the Indian state of Kashmir around the 9th century. At its core, Non-Dual Shaivism emphasizes the concept of consciousness as the ultimate reality, and views liberation as the ultimate goal of human existence.

According to Non-Dual Shaivism, the ultimate reality is not a physical or material entity, but rather the pure and infinite consciousness that underlies all of existence. This consciousness is known as Shiva, and is considered to be the source and essence of all creation. Non-Dual Shaivism teaches that all beings are ultimately manifestations of this consciousness, and that the goal of life is to realize and merge with this ultimate reality.

The concept of liberation, or moksha, is central to Non-Dual Shaivism. It is seen as the ultimate state of freedom and fulfillment, where one transcends all limitations and experiences pure consciousness. This state is known as Shiva-consciousness, and is described as an eternal and blissful state of unity with the ultimate reality.

Non-Dual Shaivism teaches that liberation is not something that can be achieved through external means or through following religious rituals and practices. Instead, it is an inner realization and awakening to one's true nature as pure consciousness. This realization is known as self-realization, and is considered to be the key to liberation.

The path to liberation in Non-Dual Shaivism is known as Shaiva yoga, which involves practices such as meditation, self-inquiry, and contemplation. These practices help individuals to quiet the mind and transcend their limited sense of self, allowing them to experience the pure consciousness that is their true nature.

Non-Dual Shaivism also emphasizes the importance of a guru, or spiritual teacher, in the journey towards liberation. The guru is seen as a guide who has already attained self-realization and can help others on their path towards liberation.

In conclusion, Non-Dual Shaivism views liberation as the ultimate goal of human existence, and teaches that it can be attained through self-realization and merging with the ultimate reality of pure consciousness. Through practices such as meditation and guidance from a guru, individuals can transcend their limited sense of self and experience the eternal and blissful state of Shiva-consciousness.
