Channeling is a method of trying to communicate with the spirit world that has existed since antiquity. Most modern channelers learn the art through the practice of Eastern meditation. This mildly altered state of consciousness enables the channeler to psychically perceive spirit messages. These manifest themselves as a “thought voice,” which is perceived in the stillness of the medium’s mind. Experienced mediums can enter into a trance state whereby the spirit entity takes direct control over the medium's voice, speaking through it in an accent quite distinct from the medium's normal mode of speech.
Ten mediums—five less expert and five experienced—were injected with a radioactive tracer to capture their brain activity during normal writing and during the practice of psychography, which involves allegedly channeling written communication from the "other side" while in a trance-like state. The subjects were scanned using SPECT (single photon emission computed tomography) to highlight the areas of the brain that are active and inactive during the practice.
In 1785 C.E., the French occultist Eteilla (Jean-Baptiste Alliette) became the first professional tarot diviner. He popularized the use of the tarot as a divinatory tool to a wide audience, and was the first to develop and publish a set of correspondences, linking the cards to astrology, the four classical elements (earth, fire, water, air), and the four humors (black bile, yellow bile, blood, and phlegm). These correspondences are still useful today.
After drawing your cards, revisit your initial question to ensure that it has been addressed properly. A good tarot guide can help you interpret the images you see on the tarot cards, but there’s really no substitute for personal reflection. As with any skill, practice makes perfect, so use this tarot tool often (daily, if possible), or order a set of Astrology Answers Master Deck Tarot Cards and practice at home!
