long story made very short:
was a rabbi
kept to the full letter of Halachah, but always poskined the most makel shita he could search out.
came to Olam Ha Bah
court said, excellent record, no need for weighing, no Gehinnom, straight to Gan Eden for you.
brought to a small bare room with a table and straw mattress, nothing else.
he said: “THIS is Olam Ha Bah!!”
he was told:”according to some shitas.”
