i cannot help u providng info but i can tell u onething
a person without brahmagnyanam is not brahmin eventhough he born in brahmin family and a person with brahmagnyanam is a brahmin eventhough he borns in sudra family
lord Vishnu is shrustikartha
brahma done many years penance(thapasya) he dont know where he came from ,later he saw lordvishnu ,and came to knew that he is his god,therafter shiva also came from vishnu
Narayana made himself into Vishnu,shiva,brahma who r leads of shrusti sthithi laya
Just pray god with whole heart ,try follow him means try to behave like good ,manava seve maadhava seva
onemorething
if u tear down when u see vishnu that means u r blessed
according to bhagavatham
brahma created people according to their mentalities and then gave them names
brahmins-the people think exactly like vishnu ,means they have vishnu gnyanam like saatviks
raju- they r like vishnu heart ,like satva rajo gun
vysyas from his thighs
sudras and etc from vishnu's feet.
if a person borns in a brahmin family he is not brahmin according to lord vishnu ,if u try to be like his wisdom then u will be brahmin understand.
these all caste things people have created
try to be pure ,pray lord vishnu wholeheartedly ,he is ther everywhere
Read Bhagavatam stories it will show u what god is
they r more powerful than mantras ,bhagavdgita
This is for u
'NaarAyaNika-Nishtasya yaa yaa vrutthi: tadharchanam
yO yO jalpasya sa Japa: Tath dhyAnam yannirIkshaNam
Tath PaadhAmbhavathulam Theertham tath ucchisshtam SupAvanam
tadhukthimAthram manthraagryam tath sprushtam akhilam Suchi
(meaning): For that One , who thinks all the time about
Sriman NaarAyaNan , whatever his karmAs (activities) are ,
they are equivalent to Bhagavath AarAdhanam .Whatever he
speaks about are the equivalents of Japam of MahA manthrams.
Whatever he sees are the equivalent to Bhagavath DhyAnam .
The water associated with his feet are matchless sacred
waters (like GangA Theertham).The left overs from his
eating are sacred to partake.All his speeches are the loftiest
of Manthrams .Whatever he touches becomes pure and pious.
Each of the samhithais have treasures housed in them
by our EmperumAn , MahA Lakshmi and Maharishis .
