Q&A: Plane of consciousness
How do we know what plane of consciousness we are in during meditation?
A seeker can be aware of the planes of consciousness only when he is on the verge of realisation. An ordinary aspirant will not be able to know, and also it is not necessary for him to know.
There are seven higher worlds and seven lower worlds. A spiritual Master can easily be in all these fourteen worlds at the same time and see things that are happening in all the worlds. An aspirant can also be in more than one world at a time, but he will not be able to know which worlds they are. Only someone who is advanced in the spiritual life, someone who is about to step onto the highest rung of the spiritual ladder, will be able to see in which plane of consciousness he is staying during his meditation. For realised souls it is very easy.
Your spiritual Master can tell you which plane a particular experience has come from. If he tells you that a particular experience comes from the vital world or the mental world, then in the future when you get a similar experience you will be able to know that it comes from that world.
