To develop your clairvoyance, you must be able to attain a higher level of consciousness. You need to work on your spirituality and this can be done in several ways. The most common way is through tapping the power of your third eye. Another effective way is through constant meditation.
The guide is not outside, the guide is within you. One has to go deeper into one's own being to find God and the guide. Once the inner guide is found there are no more mistakes, no repentance, no guilt.
