All Buddhists texts acknowledge the Four Noble Truths. The Four Noble Truths are not disinformation. They are simply the Four Noble Truths. The Four Noble Truths are not obvious and they are worth studying in depth:
MN141:8.1: “Near Benares, in the deer park at Isipatana, the Realized One, the perfected one, the fully awakened Buddha rolled forth the supreme Wheel of Dhamma. And that wheel cannot be rolled back by any ascetic or brahmin or god or Māra or Brahmā or by anyone in the world.
MN141:8.2: It is the teaching, advocating, establishing, clarifying, analyzing, and revealing of the four noble truths.
MN141:8.3: What four?
MN141:9.1: The noble truths of suffering, the origin of suffering, the cessation of suffering, and the practice that leads to the cessation of suffering.
The Buddha also instructs us to determine by our own practice what is true. We have to study and practice with proper attention to what is skillful in the context of the Four Noble Truths.
MN80:16.5: Let a sensible person come—neither devious nor deceitful, a person of integrity. I teach and instruct them.
MN80:16.6: Practicing as instructed they will soon know and see for themselves,
One can get lost in the vast sea of books about Buddhism. But at some point, we always end up studying the suttas and discussing them with teachers and good spiritual friends. The Pali Canon or Tipitaka is an excellent resource that has been extensively verified and compared with other historical references in many countries. We no longer speak Pali, and therefore must rely on translations into our own language. Such translations can be found in many places (e.g., suttacentral.net). However, in our search for truth we will often need to learn some Pali for the clearest understanding.
