Many who have been fed magazine and New Age Buddhism, a distorted, modernized, or sanitized version of Buddhism are startled to learn of true esoteric doctrines. These are of alchemy, of tantra and magic, of hells and demonic or parasitic forces that are hostile to life, hate humanity and are sworn enemies of the Dharma. So much of Buddhism is concerned with warding off these effects, so much of empowerments conducted to protect, some much ritual and energy expended to create barriers and thwart attacks of esoteric entities that feed upon one.
These are psycho-spiritual parasites that also drain the body. It is a feeling of foggy mind, of dissipated energy, of always tired, malaise, what moderns call depression. But it is beyond internal and external mere human frailty, it is an insidious, bewitching type of menace. One that whispers spells in inner mind, that casts doubt into the heart and sullies the spirits making the world wearisome and life a burden. It is interrupting meditations, it is robbing sleep or making nightmares. It is a sense of bad luck, ill will, negative sentiments from peers and casual encounters. All of these build and build, estranging one from self and true health and contentment.
Demons might assist those who torment you, raise them to higher levels, especially for those on the Path. Those who seek the Way, who endure, who strive will attract the help of Buddhas and Gods, but also the jealous and malice of demons who envy a human for their precious incarnation, their organic free will, and their once and future Buddhahood. They are hungry ghosts, parasitic entities who did the anti-Dharma and become saints of the Buddhist hells and dark forces that hate the Gods, Immortals and Siddhas and Buddhas. They are ones to exploit every fear, vulnerability, every weakness, but also every hope, human instinct, and weaponize compassion and mercy even to cause ruin and chaos.
