Unfortunately, the Sun is in Libra right now. This is not a good time for this kind of working. Wait until the Sun enters Scorpio, on October 22nd, and start this working on a Sunday during the hours of the Sun. The Solar Chakra rules willpower, etc.
On a lesser degree, Mars also rules these in the manner of drive, taking action. Mars is in Virgo right now (not ideal, but not terrible) but will enter Libra (sign of fall) on October 22nd. You can start a working for your Sacral Chakra this Tuesday, October 17th during the hours of Mars. This is the last chance before Mars enters Libra. After that, you would have to wait until December12th, when Mars will be in Scorpio (Co-ruling sign).
