General Book of the Tarot, by A. E. Thierens, , at sacred-texts.com
TRADITION: Effect, realisation, accomplishment; positive certain fulfilment of what is presaged by the neighbouring cards, succeeding. Reversed it is said to give: Deception, bad faith, vain hope, idle promise, etc.
THEORY: It is the Fire on the ascendant, First house, and consequently must be very positive in its meaning and effect. The word 'effect' is correct here and everything in the meaning of this card must be positive in its nature. There may be some conceit and self-satisfaction, but not without goodness of heart; self-centredness rather. The person indicated by this card must be a good sportsman and honest above all. So we can see no reason whatever, even in weak cases for addictions such as 'bad faith,' etc. Neither can we see 'prudence' in it, as one version has it. The force in it does not tolerate contradiction nor delay, does not reason, but acts at once.
CONCLUSION: Honesty, positive attitude, sport, self-centredness and confidence in one's self, self-reliance, certitude, accomplishment, directness, no attention paid to other people's standpoint. Means to the querent: go ahead, you will succeed. Prompt arrival of things. Strong affirmative answer on questions. The effect is certain.
