One God, the Gurus and Sikh Beliefs about Humanity
Ik Onkar — There Is Only One God
At the very heart of Sikhism is an absolute and uncompromising belief in one God. The symbol Ik Onkar (‘There is only one God’) opens the Mool Mantar, the foundational statement of Sikh belief found at the very beginning of the Guru Granth Sahib, the Sikh scriptures. The Mool Mantar was composed by Guru Nanak, the first Sikh Guru, and describes the nature of God: God is one (ik onkar), truth (satnam), the creator (kartapurkh), without fear (nirbhau), without hate (nirvair), timeless in form (akal murat), beyond birth and death (ajooni), self-existent (saibhang), and known through the Guru’s grace.
The Mool Mantar, opening the Guru Granth Sahib at page 1, is the foundational Sikh statement of faith. It teaches that God is one, true, the creator, without fear or hatred, eternal, beyond birth and death, and known through grace. Ik Onkar encapsulates the entire Sikh theological world view in two syllables.
God as Immanent, All-Pervading and Self-Revealing
Sikhs believe God is immanent — present within creation and within every person. God is not remote or absent but actively present in all things. The Guru Granth Sahib (page 1) teaches this from the very outset: God permeates all creation. Unlike traditions that emphasise God as wholly ‘other’ and separate from the world, Sikhism holds that God is found within the self and in all of existence.
God is also self-revealing: humans cannot discover God through their own unaided effort or reason alone. God reveals himself through grace (nadar) and through the Guru. The concept of the Guru is therefore central — it refers not only to the human Gurus of Sikh history but ultimately to the divine Word or wisdom of God itself. The Guru Granth Sahib (page 294) describes God as personal, as creator and as Guru — one who teaches and guides. This makes God in Sikhism both transcendent (beyond human comprehension) and immanent (intimately present within all).
Sikhism uses many names to describe the one God, reflecting the richness of divine qualities. Among the most important are:
Waheguru (‘Wonderful Lord’) — the most commonly used Sikh name for God in devotional practice. It expresses awe and wonder at the divine. Sikhs use ‘Waheguru’ as a meditation name, repeating it to focus the mind on God.
Satnam (‘True Name’) — found in the Mool Mantar, emphasising God’s nature as truth. Akal Purakh (‘Timeless Being’) — emphasising God’s eternal existence beyond time and death. Kartapurkh (‘Creator Being’) — emphasising God as the active creator and sustainer of all existence. These names come from the Guru Granth Sahib and are used in prayer and meditation.
The Role and Purpose of Humanity — Mukti
Sikhism teaches that the human life is a precious and rare opportunity. Sikhs believe in karma and rebirth: the soul passes through many forms of existence before reaching human life. Human birth is the crucial stage in which the soul can choose to turn towards God. The Guru Granth Sahib (pages 2 and 11) teaches that without God’s name, people waste this precious human existence wandering in spiritual ignorance.
Mukti is the Sikh term for liberation — the ultimate spiritual goal. It is understood as the union of the soul with God, ending the cycle of rebirth. Sikh teaching pictures this liberation as the soul merging with God, as a light blends into the Light or a drop of water returns to the ocean. The Guru Granth Sahib (page 43) teaches of the joy of this union.
Mukti (liberation) is achieved through simran — meditating on God’s name (Nam). The Guru Granth Sahib (page 125) teaches that by meditating on God’s name, a person becomes a gurmukh (one who faces the Guru) rather than a manmukh (one who is self-centred). The gurmukh lives in harmony with God’s will; the manmukh is driven by ego and desire.
Gurmukh and Manmukh
One of Sikhism’s central distinctions is between the gurmukh (one who faces the Guru / God-centred person) and the manmukh (one who is self-centred or ego-driven). The gurmukh meditates on God’s name, performs sewa (selfless service), lives honestly and treats all people as equal. The manmukh, by contrast, is trapped in haumai (ego or self-centredness) — the primary barrier to mukti in Sikh teaching. Haumai leads to attachment to the material world, pride and self-interest, which generate bad karma and further rebirth. The Guru Granth Sahib (page 125) teaches that the gurmukh is absorbed in God’s name and attains liberation.
The Sikh Gurus strongly emphasised that spiritual life should be lived within the world, not withdrawn from it. This makes Sikhism distinctively a householder religion. The ideal Sikh life combines three core principles: Nam Japna (meditating on God’s name), Kirat Karni (honest labour — earning one’s living through honourable work) and Vand Chakna (sharing with others — contributing a portion of one’s income or time to the community). Together these principles shape a life of spiritual devotion embedded in everyday responsibility.
Family life is central to Sikh teaching. Unlike traditions that regard celibacy or withdrawal from the world as the highest path, the Sikh Gurus taught that God can be found within family life, work and community. The family is considered the basic unit of Sikh spiritual community, and children are to be raised in Sikh teaching from birth. This emphasis on family life means Sikhism presents a vision of holiness that is accessible to all, not only to monks or ascetics.
