Losing a loved one is a traumatic experience for anyone. Sometimes people who are emotionally upset, hug and kiss the body of the deceased. This may however be harmful for both the person and the subtle-body of the deceased.
The proportion of excretory gases expelled from the dead body is high. Hence the area around the dead body is charged with distressing frequencies. This negatively charged area is conducive to the functioning of ghosts (demons, devils, negative energies, etc.) therefore increasing their activity.
By kissing the hand or forehead of the dead body the distressing frequencies on the skin of the dead body can enter that person. As the immediate area is charged with distressing frequencies, the person who goes to kiss the dead body also gets charged with the distressing frequencies and runs the risk of being severely affected by ghosts (demons, devils, negative energies, etc.).
If the person who kisses the dead body is affected or possessed by ghosts then through the medium of his touch the ghosts in him can enter the dead body and take control of the body. They can then trouble its subtle-body thereby creating obstacles in its onward journey.
People involved with the funeral by necessity need to touch the body of the deceased to prepare it for the funeral rites. This is a professional hazard. For example, the staff in Radiology (X-ray) department by virtue of their profession run the risk of exposure to harmful X-rays. Hence they wear lead shields to protect themselves from the radiation. Similarly, as the people involved with the funeral too run the risk of being affected at a spiritual level, it is recommended that they repeat the spiritual protective chant of Shrī Gurudev Datta while performing their duties. It is also strongly recommended that they persevere with spiritual practice on a daily basis. The spiritual practice needs to conform to the six basic principles in spiritual practice, else it is of little value in obtaining sustained protection.
