What is Yajnya?
Yajnya is the science of purification of the atmosphere through the agency of fire given through Vedas, the ancientmost body of knowledge known to humankind.
Agnihotra is the basic Yajnya. This science is now presented as HOMA Therapy. The terms HOMA and Yajnya are used synonymously here.
All this knowledge was given in a language called Sanskrit which was nobody's mother tongue at any time on earth. All languages of the world have words coming from Sanskrit. Sanskrit does not have a single word coming from other languages. Sanskrit has all the vocabulary required by modern technology and technology yet to come. Sanskrit is the language of interplanetary communication.
Along with creation Almighty Father gave Vedas. The word Vedas is the noun from the verb 'vid' meaning to know and hence Vedas means knowledge.
In the course of time, much of this Vedic knowledge was lost. It is now being resuscitated to get us out of the polluted conditions in which we find ourselves today.
