Borrowed this book from Gurdwara Sahib library: Concepts of Sikhism by Pritam Singh Gill, Formerly Prinipal Lyallpur Khalsa College, Jalandhar. It was first published in 1979 by New Academic Publishing Co, Mai Hiran Gate, Jalandhar. I'm reading the 2004 reprint. It's really quite good - I encourage you to get a copy and read it. For a taster, and the purpose of review, here's what Ji says about Maya: A. What is Maya? Maya is one of the basic concepts of Hindu Philosophy. In discussion of all philosophical topics, the concept creeps in one from or the other. According to this concept, the Universe if a mere illusion, a deception, a delusion ; that which is not a reality ; that what is only apparent ; Reality is Brahman only ; the rest that is seen does not exist ; it is unreal. Thus life in this world is of no importance. This illusion is called Maya. B. Maya is Sikhism : The concept of Maya in Sikhism is different. Sikhism believes that the Universe does exist but it is not exactly what it physically looks like ; it is not, therefore, real ; its appearance is different from what it actually is. In Sikh Scriptures, the word Maya is used in the following different senses : 1. Physical World : The physical world is not what it looks like ; besides matter it has another very subtle content in it which cannot be known by the senses and it is that subtle content which determines the entire nature and function of the material universe. Without that it is incomplete. That content, therefore, has more importance than the matter. This subtle content is the 'spirit' (Atma), which is a part of Supreme Spirit (Param Atma), the Creator of the Universe. That is the dominant content and must, therefore, be of foremost importance. 2. Sensual Pleasures : <snip> ... So to run after the physical pleasures of the world is to run after an illusion which is sure to mislead man. 3. Material Wealth : <snip> ... So money is also termed Maya because it cannot purchase spiritual satisfaction. <snip> 4. The Phenomenal World The phenomenal world is called Maya because it changes ; it is not permanent ; it is not what it looks like. <snip> Books: still better than the Internet.
