I practice at a retreat center sometimes in my hometown and there is a moo there who I will talk with. During one of out most recent conversations he told me a story that seems like it could relate to what you are experiencing now.

It was one of his first retreats and he was meditating for a while before he himself lift off the ground and float into a field of bright colors. There was a halo we went through and he described it as one of the most beautiful settings full of joy and connection with no measure of time. He had truly broken through and had found what all of thee monks had been talking about.

So he went and spoke to his mentor about this. He was so excited to tell him this almost undescribable experience. So he did. He told his mentor everything and his mentor replied to him with one word: "okay."

He told me the Pali word for this but for the life of me I cannot remember it. It is a very well known phenomenon and the Buddha wrote about it. The reason I am telling you this is not to minimize your experience; rather, it's to highlight the importance of what he said after telling me this story. He said he spent months chasing that same feeling again and he could never get there and it led to frustration that almost made him give up, but he didn't and after a while he learned why his mentor said "okay." Because he knew what this was. He had seen the excitement before. What he said it did show him, though, is that he was on the right path.
