Pl explain science examples given in Book "Nyneshancha Sandesh" page26

Jai Sadguru,

In the book "Nyneshancha Sandesh" (page no. 26) Sadguru gives some examples in science to explain the process of obtaining premsukh by namsankirtan.
I have following confusions:
1. "Kimayagar converts iron into gold or paris-touch converts iron into gold."
Is it scientifically true?
2. "If object continuously rotate in the sky, it makes noise and disappears. If similar noise
is made by mouth or instrument, that object will reappear"
About which instrment (like Radio, TV) or theory (wave theory,matter-wave relation) Sadguru speaking? Please explain to understand more.
3." When man became angry, his injected blood to animal has power to kill the animal"
Is it scientifically true?

My thinking are:1. Iron can not be converted into gold (In future may possible)
2. Body fluids like harmones may change by ANGER, but blood not change much to kill somebody after injection.

Lot of science examples which may not availabled on the first edition of book ( year 1961)
can be utilised now to explain Sadguru's Divyabodh.

Jai Sadguru, Jai Jeevanvidya
