In one sentence, describe what the following article is about: Reiki is a Japanese healing technique that was developed in the 1920s by a Buddhist monk named Mikao Usui. Like many other forms of energy healing, Reiki involves the practitioner gently touching various points on the patient's body. Scientific studies of Reiki therapy have demonstrated that it is effective for reducing pain, anxiety, fatigue, and stress, and that it may be especially useful for patients dealing with chronic illnesses or recovering from difficult surgeries. Read up on the history and therapeutic benefits of Reiki at the Center for Reiki Research website: http://www.centerforreikiresearch.org/ In order to become a Reiki practitioner, you must learn from a qualified Reiki master. While there is no one organization or governing body that determines who can be qualified to practice Reiki, there are a variety of private companies and organizations that offer Reiki training, certification, and licensing. Ask around among people you know who practice Reiki to find out where they trained, or do an online search for Reiki training in your area. You can search for a teacher or practitioner registered through the International Association of Reiki Professionals here: https://iarp.org/find-reiki-practitioner-teacher/ Although the stages of Reiki training may vary depending on your school or instructor, it is typically taught in 3 stages or “degrees.” The first degree focuses on teaching students simple techniques that they can use on themselves and friends or family. You will learn about the history and precepts of Reiki, as well as basic healing techniques.  First-degree training typically takes only 8-12 hours to complete, although some beginning courses may take longer (e.g., 1-2 days). The cost of first-degree or beginning Reiki training may vary depending on your teacher or school, but introductory classes often cost around $200 USD.  Training may include the basics of hand placement, meditation techniques, and hands-on practice. In many Reiki training programs, the second stage of learning involves the use of distance healing. These techniques emphasize using mental focus for indirect manipulation of energies, rather than directly laying hands on the body. These techniques may be useful in situations where direct touch is inappropriate or impossible (e.g., for relieving pain from open wounds).  Different instructors or schools may have different prerequisites for second-degree training. For example, you may be required to have practiced first-degree Reiki self-care for at least 6 months or to have completed a certain number of supervised clinical practice sessions.  Check with your teacher or school to find out how long the training lasts and how much it will cost. Second-degree training may last 1-2 days to over a week, with prices varying from around $300 USD to $600 USD or more. The third and final level of Reiki training is mastery. Once you become a qualified Reiki master, you can both practice Reiki and teach it to others. The training required to become a Reiki master is in-depth, and may take a year or more to complete. The cost of Reiki master training may vary depending on your school or teacher, but master programs can cost around $1600 USD. There are many different ways to practice Reiki. Some people may prefer to limit their practice to self-care and therapy for family and friends. However, if you are a more advanced practitioner, you might consider operating a private practice from your home or a rented space. Some physical therapists or healthcare providers also choose to incorporate Reiki into their regular practice.  If you choose to become a private practitioner, consider purchasing professional liability insurance.  If you'd rather not try to set up your own business, consider working or volunteering with a clinic, hospital, physical therapy center, gym, or yoga center in your area that offers energy healing or holistic medicine services. Consider becoming a member of a professional organization, such as the International Association of Reiki Professionals (IARP). Members of the IARP must be practitioners (at any level) or teachers of Reiki, and must pay a membership fee. The basic yearly fee is $169 USD.
Summary: Familiarize yourself with Reiki. Find a Reiki master in your area. Take a first-degree training class to learn the basics of Reiki. Complete a second-degree course to learn more advanced techniques. Become a Reiki master with third degree training. Establish your Reiki practice.

Problem: Article: It is possible to connect your guitar directly to your laptop through the device’s audio-in port. This port is typically located on the side of laptops, near the headphone-out port. You may see one of the following icons next to it: a microphone or a circle with two triangles. While the average guitar cable has a ¼” phone jack on each end, the audio-in port requires a ⅛” stereo plug. You may purchase a guitar cable with a ¼” phone jack on one end and a ⅛” stereo plug on the other end OR you may purchase an ⅛” stereo plug adapter to use with your standard guitar cable.  Your laptop’s audio-in port may require a stereo plug with a TS (Tip/Sleeve) connection or a TRS (Tip/Ring/Sleeve) connection. If you are unsure which tip your computer requires, consult your laptop’s manual.  If your laptop does not have an audio-in port, you will need to purchase an interface or a special cable that plugs into your audio-out port, also known as a headphone jack. These products allow you to use your audio-out port as an audio-in port. These products are sold at a variety of price points and vary in quality. You may also use these devices with your phone and tablet. If your laptop does not have a headphone jack, you can purchase an adaptor that plugs into your USB port. Insert the ¼” phone jack into your guitar. If you are using a ⅛” stereo adapter, place it over the remaining ¼” phone jack. Insert the ⅛” stereo plug into your laptop’s audio-in port. You can listen to your guitar through your computer’s speakers, a set of external speakers, or a pair of headphones. If you are using external speakers or headphones, insert the speaker cable or headphones into your laptop’s audio-out port. Strum your guitar to test the signal.  If you are using your laptop’s internal speakers or a pair of headphones, you may notice that the signal is relatively weak. This is due to the fact that the laptop’s audio-in port are not capable of amplifying the signal. A set of external speakers, however, will act as an amplifier.  You may also experience a significant delay, or a gap between when a sound is inputted into the computer and when you hear that sound.  Before you can hear your instrument, you may need to download and/or open recording software. If you can not hear your guitar, open your computer’s sound settings. Make sure your sound is not muted. Make sure the correct port or device is selected (audio-in, audio-out, headphone, microphone, etc.). For specific instructions, consult your computer or device’s manual.
Summary:
Locate your computer’s audio-in port. Purchase the correct cable or adapter. Plug your guitar into your computer. Test the signal.
