Do yakṣiṇīs exists ? Can they temper with human life ? The young lad whose life was getting destroyed

The young boy worked in some tech firm. Six feet tall guy who was smart and intelligent. He appeared totally fine and he was undergoing Venus daśa and Venus was exalted in 8^th house but in gandānt. Everything was fine until the Praśna was casted.

There was some strong aberration in Praśna.

There was no bad sign visually speaking but there was something very wrong. His life was getting destroyed slowly because of an invisible power that use to sexually molest him every day. Though he appeared fine but he was very weak. He used to collapse in office many times. The problem was that this power was not visible at the time he came.

It was not an appropriate time to cast detailed Praśna so took some time off. Did Praśna again after pooja. Moon was with a powerful upgraha occupied rohiṇī indicating female form of yakṣa.

Saturn indicating Vyanthara class. The lord was placed in 6^th house of enmity again indicating yakṣiṇī. Moon was vargottama and exalted. All in all, a powerful strong yakṣiṇī was creating trouble.

He was sent to a powerful temple controlled by Muni and yakṣa but it did not give him relief. The thing was that this yakṣiṇī was smart. She never used to enter the office so nothing could be detected. He also went to a Śrī Anjaneya Sadhak. However, he was not able to cure him though he told him the same thing which was seen in Praśna.

Then he was given a power nāma japa. He was told to do it every day for a complete year (for 2 hours/day). This intense sādhana and persistence on his part finally gave him relief. Bhagavān Śrī cured him off his troubles.

The important part is patience and persistence. Most of the people afflicted usually lack these two. They have lots of questions but they failed to do their own part which results in no escape.
