Jesus, Krishna, Gautam Buddha and Muhammad all gave people the elixir in a bowl but people rather than realizing the value of the bowl’s content preferred the bowl. The elixir has leaked, but people have embraced the empty bowl regarding it as everything. After the elixir leaked, so many defilements have filled the bowl or the religion as people have added their interpretation.
If the religion doesn’t help the person to connect directly with the Supreme Being, you are absolutely correct. If the religion teach how to make this direct contact possible, it is a vehicle that the Supreme Being can use.
