The human body consists of two things, the part that belongs to earth and the inner heart(feelings, desires, wants).
The part that belongs to earth eats from the earth's food, drink. It's visible and can be touched. Another thing we most know is how the part that belongs to earth is meant to vanish in its nature so as all things in this world are meant to vanish.
The inner heart takes it's provision from things that are not meant to vanish or end, like the remembrance of god, heaven, hell. Things that will continue to be always.
That's why when we pray to god and mention how great he is or mention his attributes or read his book, we are in the process of feeding our heart just like we feed our bodies.
Praying to god is not about the words or the movements we do, most importantly, it's about our consciousness of him that will drop the white droplets to our dark fuggy hearts.
That's how i express my spirituality, through the mind, words and actions.
