The sixth chakra involves intuition and spirituality. There are many ways to help improve your abilities in this area.
First, the color associated with the sixth chakra - or the brow / third eye chakra - is purple or indigo. Surround yourself with this color. Wear clothes in this hue. Wear amethyst and flourite, and focus on crystals of that color. Change your desktop theme to involve this color, find ways to surround yourself with this aura.
Next, it's time to add some more senses into this. Find some camphor or patchouli insense or aroma. Purple candles are also helpful in this situation.
Find ways to focus your attention on spiritual matters, and to find a grounding in your life. Take five minutes each day to sit and meditate, to chant a mantra, to focus on a special symbol.
