Renuka,
There is already a real world application in ready to cook food products. The results are not achievable by technology and anyway we didn't use technology. It was purely by transfer of spiritual energy it was done.
As of now the possibility is, spiritual energy can transfer any average product into its best expression. Basically the shelf life of anything considerably increases also acquiring many desirable qualities. Amazing results were achieved on the food products.
But in all humility I will say it's my mother's involvement that really got us going. Whether the product expertise or spiritual blessings of the Almighty.
The same to a person. It enhances youth and longetivity and makes one immune to external effects.
I am on the threshold of another big milestone in spirituality. Once that happens it is the ultimate one can attain in spiritual development. It dramatically transforms everything of self into spiritual mode.
As you say current technology complicates than simplifies. Those who are not in the know are at the mercy of those who know. There is a huge huge potential for misuse and fraud.
Spiritual energy on the other hand has not only inbuilt intelligence but also inbuilt ethics as it is an interconnected energy.
I will keep you updated.
