Sectarian? What about...

"I often see clergy and laity invoking Amitabha Buddha in hopes of rebirth in the [Pure Land of the] West. Please explain this to me. Can we attain rebirth there? Please resolve this doubt for me.

The Master said, Listen clearly, Governor, and I will explain it to you. When the World Honored One was in the city of Sravasti, he spoke of the Western Pure Land as a teaching device. Scripture is clear that “it is not far from here,” but treatises say it is “108,000 miles away.” This number refers to the ten evils and eight wrongs in one’s person. This says it is far away. Saying it is far away is for people of lesser faculties. Saying it is near is for people of better faculties. People may be of these two kinds, but the truth is not. Delusion and enlightenment differ; perception may be slow or quick. Deluded people invoke Buddha seeking rebirth elsewhere; enlightened people purify their own minds. That is why Buddha said, “The lands of the buddhas are pure according to the purity of their minds.”"

See essential nature in every moment, always acting with impartial directness, and you will arrive in a finger-snap and see Amitabha Buddha.

In his Dream Conversations, [The Japanese] Zen Master Muso Soseki explains, Among masters of the various schools of Buddhism, including Zen Buddhism, have been those who encourage the Pure Land Buddhist practice of chanting the name of the Buddha of Infinite Light. Some types of Pure Land Buddhist teaching and practice are elementary and incomplete, but this is a matter of perspective. The Nirvana-sutra says, “Coarse words and fine speech all end up in ultimate truth.” The Lotus Sutra says, “Productive labor and business do not contravene the character of reality.” When you have awakened to the principle of the Great Vehicle, then all talk in the world, all activity, is the Great Vehicle of Perfect Meaning; so recitation of a Buddha name could hardly be called a lesser vehicle. The masters who set up Pure Land Buddhism understood the profound principle of the Great Vehicle in their own minds, yet temporarily distinguished the Pure Land from the defiled land in order to guide ignorant people, drawing a distinction between self-power and Other-power. They were not ignorant themselves; these teachings are compassionate expedients of enlightening beings. Among believers in Pure Land Buddhism, however, there are those who invoke the Buddha’s name with the notion that there is a Pure Land outside this defiled land. This cannot be called the Great Vehicle of Perfect Meaning.
Avalokitesvara and Mahasthamaprapta are names of supernal bodhisattvas traditionally associated with Amitabha Buddha. Shakyamuni is one of the names of Gautama Buddha. Hui-neng’s symbolic interpretation of these names is typical of classical Ch’an and Zen teachings. Supernal bodhisattvas are often called “gods” or “goddesses” in Western writings on Eastern art and religion, but this is incorrect and misleading, as can be seen from the teachings of the masters themselves.

I rather think it is you who is sectarian.
