All activities in the limitless expansion of the universe are said to have generated from a grand eternal yajna (Yagya). Atharva Veda (9.15.14) describes Yagya as: "Ayam Yagya Vishvasya Bhuvanasya Nabhih" - implying Yagya as the fundamental process of manifestation of nature. Lord Krishna quotes in the holy Geeta (3|10)

Sahayagyah Prajah SraÌta Purovacha Praja patih |
Anena Prasavishyadhvamesha Voastvishta Kamadhuk ||

Meaning: Before the existence of the cosmos, Prajapati Brahma - the eternal creator, the supreme source of existence, had originated Yagya and commenced the process of generation and growth of cosmic powers and their unlimited manifestations resulting in the creation of nature. The Yajur Veda contains the knowledge of the principles and methods of performing Yagyas as part of spiritual and scientific experiments for global welfare. The SamaVeda focuses on the musical chanting patterns of the mantras and deals with the subtle form of Yagya by defining the latter as the process of mental oblation on the surface of emotions.

Literally speaking Yagya means - selfless sacrificing for noble purposes. In physical terms, Yagya (homam, havan or agnihotra) is a process aimed at the finest utilization of the subtle energy existing in matter with the help of the thermal energy of fire and the sound energy of the mantras. The knowledge of Yagya as realized and deciphered by the Indian rishis is indeed a boon bestowed on mankind which encompasses all dimensions of divine human culture. The methods of performing Yagyas as experimented and propagated by these ancient scientists and sages contain the key to ideal maintenance of the ecosystem and the environment of life.

The science and philosophy of Gayatree and Yagya were thoroughly practiced and propagated by the saints and sages of yore. Because of their direct impact on the physical, mental and spiritual development of human life, the principles and practices of these fundamental components of the ancient Indian culture have relevance in the modern times too. Thanks to the dedicated efforts of some sacred souls and eminent scholars like Guru Gorakshnath and Swami Dayanand Saraswati, that the glory of the ancient knowledge of Yagya has not lost its glow despite traversing through the dark period of misinterpretations, aberrations and maligning during the medieval era.

The noble contributions of Pt. Shriram Sharma Acharya have been most significant in rousing the Indian cultural values since past few decades and implementing the practices of Gayatree and Yagya as scientific experiments aimed at the welfare of all living beings. This spiritual saint, social reformer, scholar and scientist par excellence is renowned as an authority on the in-depth knowledge of Gayatree and Yagya . His inspirations have revived the tradition of Gayatree - Yagyas among the masses as part of his great Yug Nirman mission of arousal of divine culture on this globe. Gurudev Shriram Sharma conveyed that adoption of the philosophy of Yagya - sublimation of creative potentials, knowledge, pious virtues, intellect and strength and limitless expansion of altruist service with eminence - in every walk of life is a true Yagya. In concordance with the quote (from Gita ) - "Yagyartha Karmanoanyatra Lokoayam Karmabandhanah", he viewed that only those actions (karmas) are noble which are performed with heartiest sentiments inspired by the philosophy of Yagya. Other actions become the cause of thraldoms preventing the arousal of the soul and retarding its march towards unification with its divine origin.

He gave logical explanation of the implication of the rituals associated with the process of performing Yagya (havan or homam) in the sacrificial fire: each step of this process corresponds to refinement, sublimation and boundless expansion. In his views, true worship of divinity is that which results in gradual refinement and virtuous elevation of personality and arousal of associated divine qualities in the inner self...
