A Yagya is a means of direct interaction with the positive forces in Creation. Vedas abound with descriptions of yagyas performed the rishis and munis to energise the manifested creation. Devas and devis would come to be a part of such yagyas. Asurs and daityas would also come…to disturb them since the Creation is a balance of the two – negative and positive – forces.

Ram and Lakshman went with Rishi Vishvamitra to protect one such yagya. 

The nature of a human being is to aid the positive forces, the devas and devis, by protecting the havan for the peace and prosperity of one’s home, surroundings and creation at large. 

Satyug was the time when devas and devis and rishis and munis would roam about freely on earth, since the positivity was at its peak. The present times, the times of kaliyug, are times of heightened negativity and so, subtler energies like yogis and gurus are rare to find in the body, and devas and devis can only be accessed in their subtle forms by invoking positive aspect of creation through certain yogic practices and acts of charity and service.

Sanatan Kriya details the amazing science of yagyas as given by the vedic rishis to induce positivity in the body as well as surroundings. The practice involves making oblations to fire using specific chants. Fire, having the ability of transformation can transform the physical into the subtle and the mantras have the ability to manifest the ability and power of devas in the physical world and also have the power and ability to control nature and normal human physical lives.

At the beginning of a yagya, a sankalp is made which indicates the purpose for which the yagya is conducted. Then the ahvahan (invocation) of specific devs and devis is done requesting them to bless the yagya.

A yagya performed under the sanidhya of a Guru, with purity thought, ingredients and the correct chants, has the effect of completely changing the environment – the weather changes, air becomes fragrant, birds perch on the trees around, there is peace and stillness within and outside and diseases disappear – these are all indicators of warding off negativity and manifestation of positive forces in Creation.

Sadhaks at Dhyan Ashram routinely conduct such yagyas for purity of homes, environment and body, the manifestations are witnessed and recorded and their effects felt by one and all.  If there is smoke in a yagya or any kind of unpleasantness, it indicates the chants are incorrect or not done by an adept. Erroneous chants can have disastrous effects and do more harm than good, therefore one must ensure yagya is performed with correct chants and purity of ingredients and thoughts.  

If you want to know whether the yagya was performed properly or not, just watch the yagya-agni at the time of purna-ahuti. You will be able to see the form of dev/devi if the invocations were successful.
