Bhagwan Vishwakarma is revered in Indian tradition as the divine architect and craftsman of the gods and the presiding deity of all craftsmen and architects. He is credited with creating magnificent palaces for the gods and designing many of their celestial weapons and vehicles. He is hailed as the worlds first engineer and the architect of the gods, responsible for designing and constructing celestial abodes, cities, and artifacts across the four yugas (ages) of Hindu cosmology. His creations are marvels of engineering, often involving advanced concepts like flying machines and indestructible weapons. He is credited with authoring Vastu Shastra, the ancient Indian science of architecture, influencing temple designs and urban planning
Maharshi Bhrigu, revered as one of the seven great sages (Saptarishis) and a son of Lord Brahma, plays a crucial role in Hindu mythology and the spiritual tradition. Known for his immense wisdom and spiritual stature, Bhrigu is credited with founding the discipline of predictive astrology (Jyotisha). According to legend, during a divine yajna, he was tasked with testing the supremacy of the Trimurti—Brahma, Vishnu, and Shiva—to decide who deserved the highest devotion. Maharshi Bhrigu's tests included disrespecting Brahma, cursing Shiva, and striking Lord Vishnu’s chest, which left the famous "Shri Vats" footprint. Impressed by Vishnu’s humility and grace, Bhrigu declared him the greatest among the Trimurti, which shaped the spiritual hierarchy and devotion in Hinduism. Bhrigu is also believed to have compiled the Bhrigu Samhita, an astrological record believed to contain detailed predictions of individual lives based on their birth charts. This grand work, considered the world’s first predictive astrology book, was created during divine yagyas meant to alleviate human suffering. Despite the destruction of many parts, a few pages still exist in Punjab.
Brahmagupta (c. 598–c. 668 CE) was an eminent Indian mathematician and astronomer whose pioneering work drastically advanced ancient science. Serving at the renowned observatory in Ujjain, Brahmagupta formalized fundamental concepts such as zero in arithmetic, introduced rules for handling negative numbers, and developed formulae for geometry including the celebrated Brahmagupta's formula for cyclic quadrilaterals. He further solved complex indeterminate equations and significantly enriched astronomical knowledge with precise computations of celestial motions, eclipses, and the length of the solar year. His contributions laid the foundation for future mathematical and scientific development in India and beyond.
