I met a tantrik from Bhangarh in year 2001. He used to do tantra practice in Jungles near Bhangarh. He informed that the spirits in Bhangarh are so powerful that one cannot even feel them when they possess a person. He was related to spirits from previous births and was working for their Moksha. Now see this in the light of adventurous visits. You will understand why one should not visit such places. Precautions don't matter here

@AnupamaDhavale I have not mentioned many things about the incident above. This girl was going to die within three weeks. She got unconscious when she reached office. It was the subtle clues that saved her. The m guy who saved her told her everything. The jinn was fully planned to take her life

Ruins are not a place for adventures. They have opened portals from where these devilish beings enter our realm and engulf the bodies. They affect is such subtle ways that the person afflicted will loose his life without any sign. I have thousands of example. A very famous example is of one person who went to kuladhara for his channel and is no more.
