Introduction to the chakra system

The human energetic system is mainly composed of a vertical energetic axis which runs through our spine from the perineum (the region between the genitals and the anus), up to the top of our head. This is our main energetic channel and it is called in India the Sushumna Nadi. On this channel, at different levels there are seven energetic centers (named chakras) that represent our link to the "reality" and the universe(s). They are located as shown in the image on the right.

One can identify the nodal axis with Sushumna Nadi, the energetic central channel that runs through our spine. On this channel, the six chakras are projected at different levels as shown in the image on the left. The seventh chakra, the crown chakra, called Sahasrara chakra is not shown in the natal chart, it couldn't be, as it doesn't relate with the material level, only with the higher spiritual worlds. It is transcendental and represents our link to the Divinity.

The other six chakras will be projected on the nodes' axis as follows:
1. Muladhara chakra or the root chakra will be projected at a distance of 30 degrees from the South Node (SN) on both sides.
2. Swadisthana chakra or the sexual chakra will be projected from 30 degrees to 60 degrees from the SN on both sides.
