Sacred ground is chosen by the masters of consciousness because in these places kundalini, the force of creation, flows very intensely and serves as an amplifier for the spiritual operations that take place there. These spots are stages for universal spiritual operations.
In the same way, the period of time between the Vernal Equinox and the full moon is another type of spiritual amplifier. Something like a God portal opens during this time and the kundalini flows very powerfully; this makes it extremely easy to carry out spiritual work and go into advanced states of consciousness. You have the wind of God’s shakti at your back.
