Can you talk more about the bolded?

For a conscious out-of-body experience the monad (self) must exit through the crown chakra. This allows the consciousness thread to remain attached so the physical body does not fall asleep. The physical brain remains connected to the remote monad, which provides real-time conscious awareness of the out-of-body experience and full recall afterwards. When out-of-body, our waking consciousness is no longer restricted by the etheric web or censored by the physical brain, so we can perceive non-physical beings and environments. The "silver cord" that out-of-body explorers often report seeing is the life thread or sutratma, which carries life energies from the monad to the heart chakra of each subtle body.
