Irregardless is a word commonly used in place of regardless or irrespective, which has caused controversy since the early twentieth century, though the word appeared in print as early as 1795. Most dictionaries list it as nonstandard or incorrect usage, and recommend that regardless should be used instead.
Practitioners may complete Reiki training programs that last anywhere from two days to a few weeks to years, depending on the level of certification desired. There is no governing body that determines the various levels, but most Reiki schools or organizations have a beginning, intermediate and Reiki master level. Beginning classes can take two days and cost about $200, while a Reiki master program can cost around $1,600 and take a year or more to complete.
In order for the Reiki healing energies to have lasting results, the client must accept responsibility for her or his healing and take an active part in it. Therefore, the Usui system of Reiki is more than the use of the Reiki energy. It must also include an active commitment to improve oneself in order for it to be a complete system. The ideals are both guidelines for living a gracious life and virtues worthy of practice for their inherent value.
