"Al" means God. El in Hebrew means God. Al is how the Muslims get Allah. So Al-chemy has to do with working with the esoteric elements inside our own personal laboratories aka our bodies. Our God given labs

There is no such thing as exoteric alchemy. That is called chemistry. They are extremely different fields. Essentially no modern chemists are alchemists.

Alchemy is about turning impressions you get from life into positively charged energy, within your body. It is about transmuting the sexual fire inside of yourself, the life force energy, and using it to create your reality. Alchemy is all about meditation, sexual transmutation, and learning to manipulate the elements within. Which in turn, eventually waaay down the road, can allow a true alchemist to control the elements outside the body. As above so below. Which is how Jesus walked on water and how Moses parted the Red Sea. Because they were both master alchemists

There's an incredible 6 part lecture series that breaks down real, internal, esoteric alchemy here for anyone who is interested. This is as good as it gets for those seeking true alchemy
