I see this article is not necessarily a popular read! But awareness is the key to overcoming such misaligned entities in the field. The description of "demonic entities" in the field is far from new or some extrovert fantasy. It is of course central to the story of the Buddha and his final Enlightenment sitting under the Bodhi Tree. Here is an overview of the story from the New World Encyclopedia....

In Buddhism, Mara is the demon who assaulted Gautama Buddha beneath the bodhi tree, using violence, sensory pleasure and mockery in an attempt to prevent the Buddha from attaining enlightenment. In Buddhist cosmology, Mara personifies unskillfulness, the "death" of the spiritual life. He is a tempter, distracting humans from practicing the Buddhist dharma through making the mundane seem alluring, or the negative seem positive. Buddhism utilizes the concept of Mara to represent and personify negative qualities found in the human ego and psyche. The stories associated with Mara remind Buddhists that such demonic forces can be tamed by controlling one's mind, cravings and attachments.

The stories presented are formulaic—Mara appears, tries, and fails to meddle with the affairs of Buddha or one of his disciples, and is rebuked. Most of the stories found in the Mara-Samyutta describe Mara's attacks on the Buddha while he is alone during meditation, though some also describe Mara's attempts to distract the Buddha's teaching. In every story Mara is foiled—the pattern continues in the Bhikkhuni-Samyutta, where clever Buddhist nuns are able to overcome Mara consistently. The final chapter of the Mara-Samyutta has Mara admit to his daughters he cannot overcome the Buddha and concede defeat, though later writings indicate he has not lost interest in harassing Buddha's converts. The eighth chapter of the second part of the Mara-Samyutta suggests that Mara is not an eternal being, but rather a position held by a succession of beings possessing severely evil karma. Some early Buddhists, however, rather than seeing Mara as a demonic, virtually all-powerful Lord of Evil, regarded him as more of a nuisance. Many episodes concerning his interactions with the Buddha and his disciples have a decidedly humorous air to them.

Mara is best known for his role in opposing Buddha prior to and during his enlightenment. Many Buddhist works recount this tale, and it is told in great detail in the Buddhacarita, written about 100 C.E. by the Buddhist writer Ashvagosha. As Buddha sits beneath the bodhi tree Mara is alerted to this impending enlightenment. As lord of death and sensual pleasure, Mara recognizes Buddha's success will mean an end to his reign. Though futile, he decides to make attempts at disturbing Buddha and preventing his enlightenment.

Mara attempts to tempt Buddha, both with promises of glory and pleasure, and then begins to warn of consequences for breaking away from the prince's religious and secular duties. Buddha easily rejects these, knowing they are meaningless. Mara uses force against Buddha, appearing as a hideous demon and sending an army of likewise revolting and terrible creatures, bent on the bodily destruction of Buddha. They launch a volley of arrows at Buddha, but as these projectiles approach they are transformed into flowers and fall harmlessly to the ground. Buddha invokes the earth goddess to wash away the demons in a flood—the earth goddess obliges. The daughters of Mara try to coerce and seduce Buddha, but he recognizes them as they are, and is not swayed from his goal. Finally Mara mocks Buddha, and tells him his work is for nothing, as there is no one there to recognize his achievement. Buddha responds that the earth will be his witness, and after touching the ground the earth trembles in agreement.
