Satya Sai Baba is probably the best known among the characters often referred to by the name of Guru or Santoni, his fame is due to a mixture of elements common to many of them, such as the alleged miraculous ability, the ability to materialize objects and a series of other phenomena more or less spectacular, much appreciated by their followers. In the case of Sai Baba , this mixture is particularly successful as seen by the following that the Guru was able to get around the World.
Among the many performances of the Holy Man, one of particular interest is the materialization of vibhuti , also known as the Sacred Ash, that Sai Baba produced in large quantities for its faithful. The vibhuti is in effect as a gray powder that resembles the ashes properties that are attributed to it would be simplistic to define as miraculous, especially for the health benefits that would result from its use.
It is perhaps of some unknown substance with characteristics unknown?
To answer this question, it 's definitely worth a look in-depth at the Sacred Ash , with the tools that science makes available to us: perhaps we could be faced with amazing properties!
From a preliminary observation by optical microscopy showed that the vibuthi is not a simple substance but is of the composite type , being constituted by a mixture of granules colorless ( transparent ) and white granules , accompanied by particles of dark color which , in ' together , give the color gray dust.
The morphology of the grains, the optical properties exhibited in polarized light and type of the numerous fractures observed , strongly suggest a crystalline nature of the material , which has guided the choice of the most refined methods of investigation , particularly suitable for analysis of crystalline materials ( that looks a bit ' in nature constitute the bulk of all solid matter exists) .
Now let's see the details of the individual analytical techniques employed : the X-ray diffraction , electron microscopy and microprobe chemical analysis.
But that's not all! The strange similarity of vibhuti with very common materials, and absolutely natural origin, can also be seen in other features ...
The 'Alteration of microcline
In Nature, the same characteristics are observed in potassic feldspar those that have been altered by water. The alteration proceeds with the prior training of amorphous material, followed by recrystallization of minerals of the group of clays.
|The grains of plagioclase (sodium-calcium feldspar) show altered slightly different as shown in the photo to the right (bright field, magnification 300000) in the area to the left, the darker, the feldspar is visible with its typical gemination (highlighted by the presence of lamellae) in the right area are visible irregular fringes, perpendicular to the edge of the crystal, having the average spacing of 15 millionths of a millimeter. These fringes are traces of lattice planes of a proto-crystalline phase (therefore not completely amorphous, as in the case of K-feldspar), which, at least in Nature, precedes the formation of clays.|
The chemical analysis with electron microprobe fully confirm the diagnosis of alteration of the granules of K- feldspar in vibuthi: Precisely, the composition of the microcline, in areas not altered, is that of a K- feldspar pu ; passing instead altered in parts ( amorphous ) we observe the sudden disappearance of the entry of potassium and iron .
The microprobe analysis , accompanied by electron diffraction has also allowed us to identify a large number of other mineral phases present in traces, such as amorphous silica, garnets, biotites, hornblende, smectite, illiti ... In Nature, a vast assortment of minerals can be found in sandy fluvial deposits, from dismantling of rocky bodies, by wate .
Unfortunately, as is clear from what has been presente, the analysis carried out, however sophisticated, did not provide strange results, unexpected or inexplicable, as it would agree to a substance materialized out of nowhere !
By examining together the data obtained , a scientist in the dark about what is claimed by Sai Baba about the vibhuti, easy to conclude very natural source of the substanc:
a clastic sediment , probably of fluvial origin, rather composite from both the mineralogical point of view, both from the chemical point of view , produced by advanced erosion and alteration of rocks and acidic magmatic-intrusive, such as granites.
In a word : soil , perhaps picked up on the shore of the river and some ... without recourse to amazing paranormal powers!
