Spirituality means knowing that our lives have significance in a context beyond a mundane everyday existence at the level of biological needs that drive selfishness and aggression. It means knowing that we are a significant part of a purposeful unfolding of Life in our universe. Spirituality involves exploring certain universal themes – love, compassion, altruism, life after death, wisdom and truth, with the knowledge that some people such as saints or enlightened individuals have achieved and manifested higher levels of development than the ordinary person. Aspiring to manifest the attributes of such inspirational examples often becomes an important part of the journey through life for spiritually inclined people.
