Double / Hidden Meanings In the Bible [Spirituality & Religion]

I have read several examples in the Bible that have New Age / Double meanings. At least if you read between the lines. For instance, Jesus said that his Father's home has many mansions. Some think that might mean the astral plane, different dimensional levels or the 7 chakras.

Jesus also said something about the kingdom of God is within us. Some people suggest that it might be related to Guides or meditation.

I want to find the meaning of these verses and I'd like more of them that are similar.

Any suggestions?
