However, there are differences of opinion as to the nature of the premortal existence in other Latter Day Saint denominations. The LDS Church teaches that during the premortal existence, there was a learning process which eventually led to the next necessary step in the premortal spirits' opportunity to progress. This next step included the need to gain a physical body that could experience pain, sorrow and joy and "walk by faith." According to this belief, these purposes were explained and discussed in councils in heaven, followed by the War in Heaven where Satan rebelled against the plan of Heavenly Father. Hinduism In the Bhagavad Gita, considered by Hindus to be a most holy scripture, Krishna tells Arjuna; "Never was there a time when I did not exist, nor you, nor all these kings; nor in the future shall any of us cease to be." Hinduism teaches reincarnation. Consequently, everyone has pre-existed in another form. Islam In Islam, all souls are believed to have been created in adult form before earthly life at the same time the God created the father of mankind, Adam. The Qur'an recounts the story of when the descendants of Adam were brought forth before God to testify that God alone is the Lord of creation and so only God is worthy of worship and so on the Day of Judgement, people cannot use the excuse that they worshipped others only because they were following the ways of their ancestors. Humans do not remember, as they are born with an undeveloped mind (leaving only an innate awareness that God exists and is one, known as the Fitra), and God decreed when every human would be born into the physical world.
