Naval Chakra
From Heaven and Earth- (http://www.ccp.com/~hae96/)
When this chakra is clean, then the person think only positive thoughts, then no impure thoughts or feelings can penetrate. With impure feelings and thoughts I mean egoistic and malicious. When we from the spiritual dimensions talk about the concepts pure or impure, this is what we mean, and nothing else. But because it is the sex chakra that stands for purity and the pure purple light, and because there has been a lot of taboos about sex, then things have been mixed up, and it has been said, that sex in itself is impure. It is by no means, sex is only impure, if it is practised for solely egoistic reasons, and/or by hurting others. Sadism and masochism are impure varieties of sexual behaviour, here one is hurting others to satisfy oneself, or one forces others to hurt oneself, thereby forcing a karmic burden upon someone else.
When two people make love, then the lights from their sex chakras are mixed, and the purple lightwaves are creating figures, whose beauty also in this case depends on the love between the parties. Two people, who really love each other, create a fantastic aura around them when making love - it can be compared to a purple forest of fairytale trees, whose flowers and leaves create an arc above the lovers, which has so powerful vibrations, that a lot of negative karma can be burned away. In other words, just by loving another person and showing it by sexual behaviour which pleases and satisfies, one can develop very much personally and in the end thereby also spiritually.
But all this implies, that there is love between the two, and it implies that there is a will to give instead of demanding - that they both at any time are prepared to give up egoistic demands in favour of giving to the other.
The purity that is reflected in ones consciousness when the sex chakra is clean means, that one lives a positive life, a life without complaining and reproaching to others, a life where one lives in accordance with the truth of life: that one is creating ones own consciousness - either as a positive or a negative impression of the world that one lives in.
