later interpolation into Gita - religious hegemony

yajna Can result inf glob warming and fill pockets of ruthwika

I got the below shloka in a email.this is the classic example of  Religious hegemony where in a particular class[Here priestly class]  enforce their thoughts on society, this is bigger sin because it is done at intellectual level, an intellectual  betrayal . This below shloka supports the school of though which says Bhagawad geetha originally had around 75 shlokas, over a period of time priestly class modified to their advantage with numerous interpolations and subtle verses along with superstitious belief. Hence we see that the best of the best interpreters[Likes of Vivekananda/Aurobindo/Tagore etc] of Hindu scriptures condemn certain aspects of Hinduism. This shloka declares clearly that Rain is produced only when a yajna is performed, which cannot be because even before 5000 years even before this yajna was born, it rained. What ever may be the interpretation of yajna, again here the orthodox will interpret this in philosophical way , but in practice we have to call the priest who does a yajna .., priests gets money and we get rain fall (?), we all know the scientific reason for rainfall. Hence modern thinkers always challenged do  a yajna and bring rains in Thar desert etc.
The reason behind this is to force the people to think in terms of shastric tradition and hence certain class will get benefited with the money earned after performing such yajnas.     Bhagavad Gita As It Is - Chapter 3 Text 14
annad bhavanti bhutani
parjanyad anna-sambhavah
yajnad bhavati parjanyo
yajnah karma-samudbhavah annat--from grains; bhavanti--grow; bhutani--the material bodies; parianyat--from rains; anna--of food grains; sambhavah--production; yajnat--from the performance of sacrifice; bhavati--becomes possible; parjanyah--rain; yajnah--performance of yajna; karma--prescribed duties; samudbhavah--born of.

TRANSLATION All living bodies subsist on food grains, which are produced from rains. Rains are produced by performance of yajna [sacrifice], and yajna is born of prescribed duties.
