Meaning: This quote comes from the writings of Helena Petrovna Blavatsky, a prominent figure in the spiritual and philosophical movements of the late 19th century. Blavatsky was a Russian philosopher, author, and co-founder of the Theosophical Society, which sought to explore the hidden dimensions of existence and the nature of reality. The quote reflects her belief in the existence of an "Absolute Essence" that underlies and gives rise to the universe.

Blavatsky's concept of the "Absolute Essence" can be understood in the context of Theosophy, a belief system that draws on ancient wisdom traditions and seeks to uncover the fundamental truths of existence. In Theosophical teachings, the Absolute Essence is often equated with the ultimate reality or divine source from which all existence emanates. It is seen as the unchanging and eternal foundation of the cosmos, beyond the limitations of the physical world.

The phrase "periodical manifestation" in the quote suggests that the universe is not a static or fixed entity, but rather undergoes cycles of manifestation and dissolution. This idea aligns with the Theosophical view of cosmic evolution, wherein the universe is seen as a dynamic and ever-changing expression of the Absolute Essence. According to this perspective, the universe and all its phenomena are in a constant state of flux, arising and passing away in a cyclical pattern.

Blavatsky's use of the term "Unknown" to describe the Absolute Essence reflects the idea that this ultimate reality is beyond the grasp of ordinary human understanding. It is a transcendent and ineffable principle that transcends the limitations of the rational mind. In Theosophy, the quest for knowledge about the Absolute Essence is often described as a spiritual journey that involves inner transformation and mystical insight.

The quote also underscores the philosophical nature of Blavatsky's work. As a philosopher, she sought to engage with the deepest questions about existence, consciousness, and the nature of reality. Her writings often blend elements of Eastern and Western philosophy, drawing on concepts from Hinduism, Buddhism, Neoplatonism, and other traditions to present a comprehensive worldview that transcends cultural and religious boundaries.

In the broader context of philosophical thought, Blavatsky's quote resonates with perennial themes that have preoccupied thinkers throughout history. The idea of an underlying, transcendent reality that gives rise to the observable world has been a central focus of metaphysical inquiry in both Eastern and Western traditions. Philosophers such as Plato, Plotinus, and Shankara have grappled with similar notions of an ultimate reality that transcends the realm of appearances.

In conclusion, Helena Petrovna Blavatsky's quote encapsulates key aspects of her philosophical and metaphysical worldview. It reflects her belief in an "Absolute Essence" that serves as the foundational source of the universe, as well as her emphasis on the dynamic and cyclical nature of cosmic manifestation. Furthermore, the quote highlights the deep philosophical underpinnings of Blavatsky's thought and its resonance with broader currents of philosophical inquiry.
