Depending only on food for prana makes a person ordinary.
Highest persons, persons like Meera Bai, get their food directly from space through merging – Atma – Paramatman merger and elimination of the Ego boundary with Bhakti and total surrender fullness . This is when the spirit has taken over the body. At that time, the prana starts flowing unhindered. Prana flow creates uncontrolled movements and starts cutting through dirt that is holding up Prana flow all by itself. The person simply witnesses the flow. All cells, including cancers, ulcers, tumors, bulbs, swellings, irritations, Imbalances of fluids, etc are knocked out and brought to normality. This kundalini awakening. This is miracle cures – spiritual healing.
Normally we bring in the Prana to cleanse while doing or applying – medicines,aasana stretches, pranayama, music hearing, chanting mantras and fire yagnas, intellectual understanding (brahma gyan yagnyas), divine music satsangs with Saints, divine satsangs for telling the truth (Anubhava Mantapas) and lastly total surrender fullness to God as though you are totally dead to worldly concerns and on verge of death. Potency increases in that order.
Materialism is total dependence on human intervention with body functions through – medicines, radiation. Surgery, anesthesia, life support systems like breathers, kidney dialysis, heart beaters, blood transfusion, drip, heart resuscitation, etc
Life style modifications consist of self monitored changes in food, exercise, mind resting ( meditation, music), love enhancing (proper company, group silence and together ess) , Sharing Skills and Learning skills ( through living in Peace Homes and villages with infinite opportunities to learn and explore and create) , intellectual resting – through readings of holy scriptures like the Gita, the Bible or the Koran, spiritual resting ( samadhi practices – Sahaja Samadhi, Nitya Samadhi ( samadhi with eyes open), Vishista Samadhi ( seeing God in all ) , Saayujya Samadhi ( merger into Divine))
Material intervention processes require more and more specialized equipment , technology and scientific knowledge. It is all done in sanitized hospitals.
The life style change processes are done in more and more open fields. The higher ones are done on mountain tops without rush, fear or anxiety for results.
More anxiety and guarantee for results, more expensive the treatment. Time it takes is also less with high tech intervention. Lasers can correct vision almost instantly. Similar with bypass surgeries for the heart, surgeries for slip discs, liposuction for obesity, operations for tumors, ultra sound for kidney and gall bladder stones etc…
