If the SGI mentor isn't in our heart we aren't genuinely practicing Buddhism?

"The oneness of mentor and disciple starts from living life with the same spirit as one's mentor and always keeping the mentor firmly in one's heart. It is easy to talk about the way of mentor and disciple, but if our mentor isn't in our heart we aren't genuinely practicing Buddhism. 

By thinking that the mentor exists outside oneself, he mentor's actions and guidance no longer serve as a spiritual compass. In that case, when the mentor's external evaluation of oneself becomes the standards for one's actions, one will strive hard when the mentor is strictly watching, but when the mentor isn't looking, one may become calculating and stop trying one's best. The faith of such a person will not deepen, and they won't be able to achieve their human revolution.

If leaders fall prey to this tendency, they will extinguish the true spirit of Buddhism, and the pure realm of faith will become a realm of worldly affairs ruled by personal advantage and calculation. 

Only by firmly establishing the great way of the oneness of mentor and disciple in one's own heart can one further the eternal perpetuation of the law." -- SGI guidance
