A Bhajan is any type of Indian devotional song. It has no fixed form: it may be as simple as a mantra or kirtan or as sophisticated as the dhrupad or kriti with music based on classical ragas and talas.[1]It is normally lyrical, expressing love for the Divine. The name, a cognate of bhakti, meaning religious devotion, suggests its importance to the bhakti movement that spread from the south of India throughout the entire subcontinent in the Moghul era.
Anecdotes and episodes from scriptures, the teachings of saints and descriptions of gods have all been the subject of bhajans. The Dhrupad style, Sufi qawwali[2] and the kirtan or song in the Haridasi tradition are related to bhajan. Nanak, Kabir, Meera, Narottama Dasa, Surdas and Tulsidas are notable composers. Traditions of bhajan such as Nirguni, Gorakhanathi, Vallabhapanthi, Ashtachhap, Madhura-bhakti and the traditional South Indian form Sampradya Bhajan each have their own repertoire and methods of singing.Bhajans by Kabir, Mirabai, Surdas, Tulsidas and a few others are considered to be classic. The language of their works is influenced by several of the dialects of Hindi. They are widely enjoyed even among those who do not speak Hindi.

Gurbani (Punjabi: ਗੁਰਬਾਣੀ) is the term used by Sikhs to refer to any compositions of the Sikh Gurus. Gurbani is composed of two words: 'Gur' meaning 'the Guru's' and 'bani' meaning 'word'.
Extracts from Sri Guru Granth Sahib ji are called Gutkas (small books) containing sections of Gurbani.

Prayer has been an essential part of Christianity since its earliest days. Prayer is an integral element of the Christian faith and permeates all forms of Christian worship.Prayer in Christianity is the tradition of communicating with God, either in God's fullness or as one of the persons of the Trinity.
In the early Church worship was inseparable from doctrine as reflected in the statement: lex orandi, lex credendi, i.e. the law of belief is the law of prayer. The Lord's Prayer was an essential element of the meetings of early Christians, and over time a variety of Christian prayer emerged.
Christian prayers are diverse and may vary among Christian denominations. They may be public prayers (e.g. as part of liturgy) or private prayers by an individual. Prayers may be performed as petition (or intercession), thanksgiving, blessing (or benediction), praise or confession.
A broad, three stage hierarchical characterization of prayer begins with vocal prayer, then moves on to a more structured form in terms of Christian meditation, and finally reaches the multiple layers of contemplative prayer.Contemplative prayer follows Christian meditation and is the highest form of prayer which aims to achieve a close spiritual union with God. Both Eastern and Western Christian teachings have emphasized the use of meditative prayers as an element in increasing one's knowledge of Christ.

Qawwali (Nastaʿlīq: قوّالی; Gurmukhī: ਕਵਾਲੀ; Devanāgarī: क़व्वाली; Eastern Nagari: ক়ব্বালী) is a form of Sufi devotional music popular in South Asia, particularly in the Punjab and Sindh regions of Pakistan, Hyderabad, Delhi and other parts of India. It is a musical tradition that stretches back more than 700 years.
Originally performed mainly at Sufi shrines or dargahs throughout South Asia, it has also gained mainstream popularity. Qawwali music received international exposure through the work of the late Pakistani singer Nusrat Fateh Ali Khan, largely due to several releases on the Real World label, followed by live appearances at WOMAD festivals. Other famous Qawwali singers include Pakistan's Sabri Brothers, Bahauddin Qutbuddin and Aziz Mian.
