The way I read playing cards, sixes are the difficult number. In general, six brings out the worst in the cards. I’ve noticed that this is a trend in Italian systems of cartomancy (althouth not in Kapherus’ system).

The Six of Hearts is the only positive card of the bunch, as it signifies the solution of trouble, adjustment and the return to happiness, health, etc. It shows peace, improvement and relax. Only when hemmed in by nasty cards it turns foul and it brings tears (which the card graphically reminds me of) and the impossibility of a solution.

The Six of Clubs is a very static card. It signifies tiredness and a situation with all work and no play and no enthusiasm. It is symbolic of subordinate work and, more broadly, it implies the inability to definitely put a problem behind you, as it keeps showing up. With positive cards, it shows the ability to reach your goal, but usually without a great sense of realization.

The Six of Diamonds is also a meh card. It is connected with insecurity, worries, confusion and indecision, especially but not exclusively of a financial nature. It shows all those situations where you can’t stop thinking about something and being tormented by it. However, with positive cards it can signify a situation that is sorted out by being resourceful, planning and making an informed decision.

The Six of Spades is a card of illness, as it figuratively depicts the wards of a hospital. It is one of those cards that is very difficult to put a positive spin on. The illness can be literal or figurative, when it symbolizes a situation of suffering and upset, or even one that is noxious or damaged. In itself, it negates reconciliations and the possibility of returning to the past, though of course the following cards may alleviate it.
