Does the sutra direct the religious practice of interfaith? This question is most important.

"If votaries of the Lotus Sutra carry out religious practice as the sutra directs, then every one of them without exception will surely attain Buddhahood within his or her present lifetime. To cite an analogy, if one plants the fields in spring and summer, then, whether it be early or late, one is certain to reap a harvest within the year."
