I have seen a question here that I have opened 7 basic chakras... n how to open 8th 9th... but is he real say what are effects of opening chakras... do you realized... tell how to open... I 'm so interested to open I also meditating... but I can't realize anything...

You have to be careful about opening them. The 8th chakra is above the head a few inches up. In psychic class they had us imagining a bright light or a sun was above our head. That is what I think opens it. It is a more advanced one. The 9th is I believe above that. You should take your time.
