It was actually the three lower chakras because those are tied to the material plane. As you move kundalini upwards, it increases in energy because the resistance increases. Moving it downwards again induces all sorts of problems, like gluttony and sexual degeneracy.
Vimalananda said celibacy and the presence of a qualified guru are vital to the success of this practice, though if you have no guru you can improvise by doing guru yoga with celestial beings.

Is there really a stomach chakra? I'm a noob but I've never felt anything there. He also says how tibetan monks never shut the root and hidden chakra. Also, just wanted to share that now i understand why the crown and third eye gets sorts activated when one meditated.... It's because of the heart beat, and certain heart beats (like when you're doing metta, for example) vibrate at such a level that those vibrations stimulate the head.

You're not supposed to feel things unless something is out of balance. I no longer get tingles or vibrations in any chakra, when I used to have strong vibrations in the third eye chakra. After it opened, the vibrations ceased.

Can you tell me what I have to expect when i open my third eye? Is it true that you see shadow people and disembodied beings? Can I see my past lives?
human
The truth is underwhelming actually, it basically allows you to get into meditative states of non-duality. The third eye looks inside, not outside.
Whether or not you get the past life siddhi depends on other spiritual attainments.

Yes an open 3rd eye means you can perceive vast amounts of life in other spiritual planes at other frequencies than our physical world. 
But you develop the skills that you practice for, so an evocation magician will develop skills of spirit communication, but an emptiness meditator will develop skill in accessing emptiness.
