Because the Mahayana sutras all possess to some extent the underlying conviction that their task was to win others over to their belief, it is very difficult to distinguish, among the intermingling of intellectual influences, exactly which ideas were borrowed and which were lent. Further, unlike the treatises of the Abhidharma, the authors of the Mahayana sutras did not lend their names to their works, but put them in the mouth of Ānanda; it is therefore all the harder to clarify the actual circumstances of transmission.

The first half of the Lotus Sutra (the theoretical teachings, called the “secondary gate”; Jpn., shakumon) is concerned with giving concrete expression to the idea of “explaining the three and revealing the one” in the “Tactfulness” chapter, giving predictions of future buddhahood to the arhats and pratyekabuddhas and including all three vehicles in the one. This reflects a powerful new viewpoint. From the time of early Mahayana and the Perfection of Wisdom sutras, the bodhisattva vehicle had been praised as superior to the others, and the possibility of arhats and pratyekabuddhas gaining buddhahood was not acknowledged. The possibility of buddhahood for women and for Devadatta, who had fallen into hell for slandering the Dharma, remained unadmitted. When a movement grew up within Mahayana demanding the potential of enlightenment for all beings through the enlarged compassion of the Buddha, the formation of the “Devadatta” chapter became a necessity. This trend reached its culmination in the Mahāparinirvāṇa Sūtra, which taught that all beings without exception possess the buddha-nature and buddhahood is possible even for icchantikas (incorrigibles), even though they have no aspiration for enlightenment (bodhicitta). This is clearly in the line of Lotus thought.

The latter half of the Lotus Sutra (the essential teachings, called the “primary gate”; Jpn., honmon), deals with the true and expedient teachings of the Eternal Original Buddha, set forth in the chapter “Revelation of the [Eternal] Life of the Tathāgata.” This development may be traced as stemming from the monotheistic tendencies of the early Mahayana sutras coupled with the growth in Hinduism of faith in a supreme deity. The idea of an eternal, original Buddha exerted an influence on the concept of Amitābha/Amitāyus (characterized by eternal light and eternal life) in the Pure Land sutras, and on Vairocana Buddha (the Dharma Body of Wisdom) of the Avataṃsaka Sūtra.

These, then, are two aspects that portray the continuity and development of Lotus thought in Mahayana sutras.
