The one administering the tonsure must be an ordained priest, and must be a monk of at least the rank he is tonsuring the candidate into. However, a Bishop (who, in the Orthodox Church, must always be a monk) may tonsure a monk or nun into any degree regardless of his own monastic rank. Jain ethics and five vows Jainism teaches five ethical duties, which it calls five vows. These are called anuvratas (small vows) for Jain laypersons, and mahavratas (great vows) for Jain mendicants. For both, its moral precepts preface that the Jain has access to a guru (teacher, counsellor), deva (Jina, god), doctrine, and that the individual is free from five offences: doubts about the faith, indecisiveness about the truths of Jainism, sincere desire for Jain teachings, recognition of fellow Jains, and admiration for their spiritual pursuits. Such a person undertakes the following Five vows of Jainism: Ahiṃsā, "intentional non-violence" or "noninjury": The first major vow taken by Jains is to cause no harm to other human beings, as well as all living beings (particularly animals). This is the highest ethical duty in Jainism, and it applies not only to one's actions, but demands that one be non-violent in one's speech and thoughts. Satya, "truth": This vow is to always speak the truth. Neither lie, nor speak what is not true, and do not encourage others or approve anyone who speaks an untruth. Asteya, "not stealing": A Jain layperson should not take anything that is not willingly given. Additionally, a Jain mendicant should ask for permission to take it if something is being given. Brahmacharya, "celibacy": Abstinence from sex and sensual pleasures is prescribed for Jain monks and nuns. For laypersons, the vow means chastity, faithfulness to one's partner. Aparigraha, "non-possessiveness": This includes non-attachment to material and psychological possessions, avoiding craving and greed. Jain monks and nuns completely renounce property and social relations, own nothing and are attached to no one. Jainism also prescribes seven supplementary vows, including three guņa vratas (merit vows) and four śikşā vratas. The Sallekhana (or Santhara) vow is a "religious death" ritual vow observed at the end of life, historically by Jain monks and nuns, but rare in the modern age. In this vow, there is voluntary and gradual reduction of food and liquid intake to end one's life by choice and with dispassion, In Jainism this is believed to reduce negative karma
