Finishing up another month of meditation. Starting to see jhana as a bit more graduated than I did before, as a sort of a life-process that isn't tied to meditation practice in itself (if that makes any sense).
One of the most common misconceptions I find regarding enlightenment is a belief that it is a single event after which the person is "enlightened." Most of the time when we have an individual who claims such an enlightenment they have none of the charisms that many of us here are reporting. Instead, I agree, enlightenment is a process and has many grades or shades, and requires a lifelong commitment to a lifestyle that supports it.
Gotten very easy to make the mind 100% silent. Generally able to keep it still or quiet for the whole of the day. Starting last week I also developed another charism, a regular warmth in my chest or heart, something I'd experienced ~3 years ago but not connected with meditation. Pops up almost every time I meditate, and sometimes follows me during the day. I do not feel like a seraphim, but I think I understand where religious authors get the fire metaphor from. =)
Going to keep working with the sound & heart charisms (especially the latter now), and see if I can use them to move into contemplation proper.
According to St John of the Cross, "contemplation" begins when the mind is still. However, it is our experience here that contemplation has many shades and nuances. The opening of the heart chakra, or regular "warmth" in you chest or heart is one of those nuances.
You did not mention the charism of sound, or kinesthetic charisms, but as you are reporting deeper meditations and more success with stilling the mind, then we should assume that those charisms persist, nonetheless.
Yes, fire as a metaphor for the religious experience is common between mystics of many cultures. Since they did not have electricity; whereas we do, then past mystics commonly used the metaphor of fire; whereas, mystics today commonly use electricity as a metaphor for the experience of energy and warmth associated with the charisms.
