There is general ledger in the heavens by which it is possible to reach out to God. There are different prayers there, reading which you connect yourself to God. If you want to knock out to the highest God it happens automatically. Person in heavens inserts id of suffering person and it works out or not admitted.
Highest God watches only most difficult situations such as danger of full annihilation. If Gods cabal over torturing men, the Highest God watches or transfers the deal to less gradated Gods.
These books are kept in common places and can be used by different Gods.
To ask to use register person shall pray and ask spiritual forces to use this ledger.
