Among all the different types of spirits you may encounter, spirit guides are the best to begin with because they are benevolent, non-physical entities who are in alignment with your best intention and are sanctioned to help you to achieve your true will. For this reason, it's best to begin spirit work and develop your intuitive or psychic senses by tuning in with your spirit guides because they are safe entities. You must give spirits permission to manifest in order to make contact with them. *Disclaimer: do not drive or operate machinery while performing this mediation.
