No. In the Jain story of Harikeshi Muni, the Yaksha Mandak is described as entering Princess Bhadra’s body as punishment for her disrespect, not Harikeshi Muni’s body. The Yaksha also later troubles the Brahmins and leaves after they repent. ( jaingpt.org)

If you meant Harikeshi Muni, the tradition presents him as being protected by the Yaksha, not possessed by him. ( jaingpt.org)
