There are two questions here so I will use two seperate answers for it...
Answ er #1
I'd say that in this case Divination is the answer while it;has been specifically designed to answer this sort of questions...
You've got various chocies when it comes to Divination related to your quesstion.
Divination is the practice of foretelling future events or accessing information and knowledge via metaphysical means and tools. Throughout history there have been many methods used from the reading of salt sprinkles (alomancy), to the interpretation of flames (pyromancy). Some of the most commonly practiced methods today include: astrology, psychic reading, palmistry, psychometry, numerology, and cartomancy.
I you case i can see that there are few things you can do by researching about different Divination forms and getting to know what to do...
For example, you can take Astrology. Astrology is the study of a person's birth date in relation to the stars and the planetary system in order to assess their characteristics and how they relate to others. Horoscopes are a portion of this method in that they may reveal general aspects related to an individual's zodiac sign. More personalized readings are done through the use of natal charts.
I also highly recommend Tarot and other different readings. . Tarot cards, fortune telling cards, angel cards, playing cards, oracle cards, etc.... The use of any style of card deck to obtain information about a person's past, present, or future is a form of cartomancy. Generally the practice of using such cards is also enhanced by other skills, such as clairvoyance, in order to offer the most valuable readings. Many psychics will use cards as a tool to aid them, perhaps to narrow the scope of a reading to specific concerns of the person.
There are hundreds of decks from which to choose. The most important thing to take into account when selecting a deck is that you should select one that you feel drawn to or a connection with...one that the artwork is appealing to you. If you don't see one the first place you look - try another source
For instance any method of divination that employs the scattering of sticks, coins, stones or similar objects is considered to be an oracle reading. Meaning you've got many chocies. The two most popular today are I Ching and Rune-casting. Both have ancient roots, Chinese and Norse/Germanic respectively.
There are many styles of psychic readings grouped together in this category of life. I gave you few known recommendations while you can read about other forms of divination which may assiste you to get what you need which is basically the answer for the question you've got.
Answer # 2
Unfortunately, this is one of those problems that just takes practice and concentration work. And indeen, meditation is the key here.
I call these kind of meditation concentration meditation. These are probably the most common and well know of all the meditations and often meditation is defined by these kinds of meditations exclusively. They are closely related to the Insight Meditation Techniques, with the difference being that Insight Meditation Techniques utilize the active application of intelligence and discernment, while the Concentration Meditation techniques use the power of focused attention to a greater degree. To some extent these meditations lay the groundwork for the Insight Meditations which need a high degree of concentration as a prerequisite to being effective.
Look at google and search for articles about methods of such meditation, you'll see that it is covered very well.
Hope it helps...
