Daily Wisdom: From the Writings of Nichiren Daishonin
The meaning of this passage is that those who obtained benefit during the Former and Middle Days of the Law received "conspicuous" benefit, because the relationship they formed with the Lotus Sutra during the lifetime of the Buddha had finally matured. On the other hand, those born today in the Latter Day of the Law receive the seeds of Buddhahood for the first time, and their benefit is therefore "inconspicuous."
