The Sikhs believe that God is formless but realisable; He is fearless, without enemies, self-created, without birth or otherwise subjected to time. The Sikh holy scripture, given the full name of Sri Guru Granth Sahib explains the various facets of God in substantial detail. This principle of one God leads to the next primary concept for the Sikhs: The concept of equality of all the human races, sects, gender, social classes, etc. The adherents of Sikhismbelieve that all peoples of the world are equal in the eyes of God; man is equal to woman; a rich person is equal to a poor man; a black person enjoys the same rights in God's domain as a white person and so on.
From this follows the next recognised belief in Sikhi that people of all faiths can reunite with God provided they follow the true path of their own religion. So the Sikh does not believe that they have a monopoly on God or are the ‘chosen’ people of the Lord. Anyone can get favours from God depending only on His or her actions and thoughts. God does not see ones colour or gender or social status when passing judgement!
Further, the Sikhs believe in the evolution of the Soul and the principle of reincarnation. The soul is believed to be a tiny spark of God’s light detached from the Almighty. This spark is separated from God and wants to become pure so that it can reunite with God. For this to happen, the Soul has to evolve and purify itself so that this reunification with the Supreme Soul can take place.
The law of Karma is another concept central to this faith. Ones actions in this life will have a direct influence on the type of life in your next existence! So to adhere to these principles, the dedicated follower must lead a disciplined personal life and must uphold the moral and ethnical rights of all the peoples of the world. So it is a must to lead a spiritually correct life at all times and to be ready to be subjected to personal sacrifices if the liberty of any weak person(s) is at stake.
Another central tenet of Sikhism is the concept of ‘Chardi kala’ – Positive attitude to life at all times. Graciously and with humility to accept the will of God at all times. Always to lead ones life unattached and untangled with the material world. Not to come under the influence of Maya – the illusionary and transient world around us. To remain detached from this world but to recognise ones duties to God and his creation.
