GOD, a term used to denote any object, of worship or evocation, signifies the belief of most modern religions in the existence of a Supreme Being who is the source and support of the spatio temporal material world. Theologians remember Him by the name of God. The fundamental belief of Sikhism, too, is that God exists, not merely as an idea or concept, but as a Real Being, indescribable yet not unknowable. The Gurus, however, never theorized about proofs of the existence of God. For them He is too real and obvious to need any logical proof.
VAHIGURU, also spelt and pronounced Vahguru, is the distinctive name of the Supreme Being in the Sikh dispensation, like Yahweh in Judaism and Allah in Islam. In Sikh Scripture, the Guru Granth Sahib, the term does not figure in the compositions of the Gurus, though it occurs therein, both as Vahiguru and Vahguru, in the hymns of Bhatt Gayand, the bard contemporary with Guru Arjan, Nanak V (1553-1606), and also in the Varan of Bhai Gurdas. Guru Gobind Singh, Nanak X (1666-1708), used Vahiguru in the invocatory formula (Ik Onkar Sri Vahiguru ji ki Fateh, besides the traditional Ik Onkar Satigur Prasadi) at the beginning of some of his compositions as well as in the Sikh salutation (Vahiguru ji ka Khalsa Vahiguru ji ki Fateh varied as Sri Vahiguru ji ki Fateh).
GRANTHI, from the Sanskrit granthika (a relaier or narrator), is a person who reads the granih, Sanskrit grantha (composition, treatise, book, text). The terms are derived from the Sanskrit grath which means "to fasten, tie or string together, to compose (a literary work)." In Sikh usage, granih refers especially to the Guru Granth Sahib, the Scripture, and the term granihl is used for the officiant whose main duty it is to read the Holy Book in public. The granth`i`s, the principal religious official of Sikhism, but should not be thought of as a "priest" in the usual sense.
GURMANTRA, Punjabi Gurmantar, is that esoteric formula or term significant of the Supreme Being or the deity which the master or teacher confides to the neophyte to meditate on when initiating him into his spiritual discipline. The concept of mantra goes back to the pre-Vedic non Aryan tradition and to the primitive cults of magic, animism and to temism. It has since been a continuing element one way or another in the religious traditions of the world and traces of it pervade to this day among the most modern of them. The occultist and the tantrist believe that mantras have power over the deity and can make it confer the desired boon or favour.
AKAL, lit. timeless, immortal, non temporal, is a term integral to Sikh tradition and philosophy. It is extensively used in the Dasam Granth hymns by Guru Gobind Singh, who titled one of his poetic compositions Akal Ustati, i.e. In Praise (ustati) of the Timeless One (akal). However, the concept of Akal is not peculiar to the Dasam Granth. It goes back to the very origins of the Sikh faith. Guru Nanak used the term in the Mul Mantra, the fundamental creedal statement in the Japu, the first composition in the Guru Granth Sahib.
GURMAT (gurmat, mat, Sanskrit mati, i.e. counsel or tenets of the Guru, more specifically the religious principles laid down by the Guru) is a term which may in its essential sense be taken to be synonymous with Sikhism itself. It covers doctrinal, prescriptive and directional aspects of Sikh faith and praxis. Besides the basic theological structure, doctrine and tenets derived from the teachings of Guru Nanak and his nine successors, it refers to the whole Sikh way of life both in its individual and social expressions evolved over the centuries. Guidance received by Sikhs in their day today affairs from institutions established by the Gurus and by the community nurtured upon their teachings will also fall within the frame of gurmat.
AKAL MURATI, a composite term comprising akal (non temporal) and murati (image or form), occurring in the Mul Mantra, the root formula or fundamental creed of the Sikh faith as recorded at the beginning of the Japu, composition with which the Guru Granth Sahib opens, literally means `timeless image`. Elsewhere, in the compositions of Guru Ram Das (GG, 78), and Guru Arjan (GG, 99, 609, 916 and 1082), the expression Akal Murati reinforces the original meaning of Divine Reality that is beyond the process of time, and yet permeates the cosmic forms. The non temporal Being transcends the space time framework and, as such, is Formless. However, in its manifest aspect, the same Being assumes the cosmic Form.
