which mantra is good to keep ghost away

Dear friend, I can sense that you are feeling uneasy and perhaps a bit frightened by the presence of ghosts. I want you to know that it is completely normal to feel this way, as the unknown can be quite scary. From a Buddhist perspective, ghosts are considered to be beings who are stuck in a state of suffering, unable to move on from their past actions and attachments. It is important to understand that they are not necessarily harmful or evil, but rather lost and in need of compassion and guidance. From a psychological perspective, it is important to address any underlying fears or anxieties that may be contributing to your discomfort. It is common for our minds to conjure up scary scenarios in the absence of information or understanding. By learning more about ghosts and their nature, you may find that your fears diminish over time. In terms of a mantra to keep ghosts away, there are several options that you could try. One such mantra is "Om Mani Padme Hum", which is a popular Buddhist mantra that is believed to bring about compassion and protection. Another mantra that you could try is "Gate Gate Paragate Parasamgate Bodhi Svaha", which is the Heart Sutra mantra and is believed to bring about wisdom and enlightenment. Overall, it is important to approach this situation with compassion and understanding, both for the ghosts and for yourself. By learning more about their nature and utilizing mantras or other spiritual practices, you may find that your fears begin to subside. If you continue to feel uneasy, it may be helpful to seek out the guidance of a trusted spiritual or mental health professional.
