Can Vastu help us gain enjoy peace?
Definitely. Along with Vastu, please check your personnel astrology as well. Because Vastu Shastra is a part of Jyothish Shastra which deals with the effect of light on human beings. If Vastu is good and astrology is also good, then nothing to beat it. If Vastu is good and if the astrology is bad, then you will be forced to leave the house and going out of town for the next job and this is exactly what is happening to many people. We do reap the benefits of our good or ad karma but knowledge is power and the mind with the knowledge is powerful with synergy. Or mind can defy bad karma.
