Something may now be inherent but wasn't always inherent. An example is a gene that has been introduced into a genome and begins to self propagate, thus becoming inherent. Another example is found in the Lotus Sutra in The Parable of the Gem in the Robe. The man inherently possessed the gem but only after it had been sewn into the lining of his robe. This is True Cause with a beginning. Only the Eternal Buddha possesses True Cause with no beginning. That is why he is the Eternal Master and to whom we owe our deepest gratitude. No one, save for the Eternal Buddha Shakyamuni, has realized the Great Law of Namu Myoho renge kyo since time without beginning. No one other than he has been sowing the seed of Buddhahood [sewing the gem in the robe] in countless people since the infinite past. Those others who have realized this Law have done so thanks to this Buddha. There is no independent realization of the Great Law. Believing there is (an independent realization of the Great Law) or mis-attributing the sartor of the gem [sower of the Law] is the source of SGI's arrogance.
