In tarot the Reversals- that is when card comes upside down, reveals a very interesting but hidden meanings. 78 cards are a lot of meanings to digest, and so simply doubling the number of possibilities to 156 individual meanings is enough to make anyone pause and reconsider if they can ever manage the endeavor of reading the Tarot.
The main idea here is that the energy of the card is present, that’s why one drew it and it showed up in the spread, but as it is mis-aligned it might indicates that the results shall not come forth in its full capacity. In this context a reversed Tarot card indicates that the energy is depleting
From another perspective, each tarot card symbolizes a particular energy, and a tarot reading reveals the collective energies that make up a situation. When one go for a reading, the actions, and intentions of the questioner align the energies of the moment with the cards to form a picture. The cards capture the energy currents in and around as one shuffle and cut.
At that moment, these energies will be at different levels. Some will be strong and powerful, others less so. Some will be just entering your life, others, moving away. How you use these energies depends on all the factors that bear on your situation. When a card is upright, its energy is free to manifest. Its qualities are available and active. When a card is reversed, its energy is not fully developed. It may be in its early stages, or losing power. It may be incomplete or unavailable. The qualities of the card are present, at least in potential, but they can't express completely.
Further every card has positive and negative meanings. For some it might predict good results, for some it can be mixed and for rest obviously onerous. One way of interpreting cards in the reverse is the fear of questioner of loosing something. Sustenance of resources can be hard or in coming time or he is prejudiced by some apprehensions.
Yet for some readers the approach to read reversal card is simply take the meanings of cards and read them opposite if they are reversed. Interpreting reversals in this way is doing injustice to the reading. Such cards have more depth and should be deciphered with caution.
In all, there is one guaranteed, full proof method to read the effects of reversals. The Tarot cards have flexible meanings, that keep changing with received wisdom, descriptions on the card, their place in the spread, the intuition of the reader and even the demeanour of the person asking the question!
