"There are no 'doctrines' espoused by President Ikeda that are not found in the gosho."

"Name one SGI doctrine that contradicts the gosho.  There are no "doctrines" espoused by President Ikeda that are not found in the gosho." -- SGI leader

Here is one example:

"At that moment, the Daishonin completed his mission as Bodhisattva Jogyo and revealed his true identity as the original Buddha of kuon ganjo, who made his advent in the Latter Day of the Law. In other words, he cast off his ephemeral status as a priest who propagated the Lotus Sutra and proved himself to be the true Buddha." -- Daisaku Ikeda (Seikyo Times July 1993 pg.47). 

There is not even the words kuon ganjo, let alone the concept of the Buddha of kuon ganjo in the entire gosho.
