Hello Reader!
Welcome to the blog page of Astrology Books of Dr. Sohini Sastri, one of the best astrologer in India.
In Vedic philosophy’s rich and vast landscape, few phrases carry the depth and spiritual potency as “Om Tat Sat.” It is more than a mantra; it is the essence of the Supreme Reality, a powerful declaration used in ancient scriptures and rituals, and a guiding principle for those on a spiritual path. But what does it truly mean? In this blog, I, Dr. Sohini Sastri, will help you understand the deeper significance of Om Tat Sat, its origins, usage, and spiritual implications as per our sacred texts.
The phrase “Om Tat Sat” appears in the Bhagavad Gita, Chapter 17, Verse 23. According to Lord Krishna:
“Om Tat Sat iti nirdesho brahmanas trividhah smritah…”
Which translates to:
“Om Tat Sat – this has been declared as the triple designation of Brahman (the Absolute Reality). By that were created the Brahmanas, the Vedas, and the Sacrifices in ancient times.”
This shows that Om Tat Sat is not merely symbolic; it is the eternal truth, the sound formula of the universe, and the foundational energy from which all Vedic rituals and spiritual activities emerge.
To understand Om Tat Sat, we must break it down:
The primordial sound, representing the Supreme Being or Brahman. It is the sound of the universe, often chanted to center the mind, align energy, and begin spiritual practices. In astrology and Vedic rituals, “Om” sets the divine vibration for any spiritual undertaking.
Literally meaning “that,” it signifies detachment from ego and material desires. When an action is performed for “Tat,” it means it is done for the Divine, without attachment to outcomes.
Meaning truth, purity, and existence, “Sat” stands for that which is real and eternal. It is also used to describe actions done in harmony with truth and righteousness.
Thus, Om Tat Sat becomes a divine formula reminding us that all true actions are those done for the Divine (Tat), in alignment with truth (Sat), and begun with the universal sound (Om).
In today’s fast-paced, material-driven world, people often seek meaning, peace, and clarity. The phrase Om Tat Sat offers a spiritual compass. Whether you’re a seeker, a devotee, or simply someone looking for peace, understanding and meditating upon Om Tat Sat can realign your thoughts and actions with higher purpose.
As a renowned astrologer in India, I often advise my clients to chant or reflect upon Om Tat Sat when:
In Vedic astrology, Om Tat Sat is often used to sanctify rituals and remove the ego-driven intentions from astrological remedies. When we perform a puja, donate, or engage in mantra chanting, adding Om Tat Sat ensures the action is selfless and divine-oriented.
From Navagraha Shanti rituals to Vastu dosha remedies, chanting Om Tat Sat enhances the energy of the practice. It acts as a seal of truth, bringing harmony between karmic action and spiritual liberation.
