You asked if i have read Isa Vasya Upanishad. Yes i have. It is indeed one of the shortest Upanishads.
You asked what does this mean: "He is the self, a-kaayam, the bodyless, there is no kaaya. When there is no body, there are no muscles." Any thoughts on what it is trying to say?" http://www.spiritualgrowth.org.in/isaupa.htm
It is saying God does not have image. I think you probably have read Yajurveda. In Yajurveda chapter 40 verse 6, it is said "shudhama poapvidham" which means "He is bodyless and pure." <Yajurveda 40:8> Hinduism is commonly perceived as a polytheistic religion. Indeed, most Hindus would attest to this, by professing belief in multiple Gods. While some Hindus believe in the existence of three gods, some believe in thousands of gods, and some others in thirty three crore i.e. 330 million Gods. However, learned Hindus, who are well versed in their scriptures, insist that a Hindu should believe in and worship only one God.
The major difference between the Hindu and the Muslim perception of God is the common Hindus’ belief in the philosophy of Pantheism. Pantheism considers everything, living and non-living, to be Divine and Sacred. The common Hindu, therefore, considers everything as God. He considers the trees as God, the sun as God, the moon as God, the monkey as God, the snake as God and even human beings as manifestations of God!
Islam, on the contrary, exhorts man to consider himself and his surroundings as examples of Divine Creation rather than as divinity itself. Muslims therefore believe that everything is God’s i.e. the word ‘God’ with an apostrophe ‘s’. In other words the Muslims believe that everything belongs to God. The trees belong to God, the sun belongs to God, the moon belongs to God, the monkey belongs to God, the snake belongs to God, the human beings belong to God and everything in this universe belongs to God.Thus the major difference between the Hindu and the Muslim beliefs is the difference of the apostrophe ‘s’. The Hindu says everything is God. The Muslim says everything is God’s.
