I do think the reader is incorrect in saying do all 3 together, you should do the honey jar & reconciliation work, but if the IS is needed then you also need to do road opener work to clear the problems of the past, then I would do the IS spell.
The spell is on this site called the Prayer of Intranquility, however it is incorrect and misses some vital parts out. It also says to do this on a Friday and during the hour of Venus, the fact is this is not a love spell and is all about getting in contact with the person again, so I would say Friday during the hour of Mercury, although it can be any time, moon doesn't need to be waning either.
The basics of the spell are 3 oils (I use Follow me Girl, Reconciliation, Commanding). You also need a candle and a cross/crucifix, this can be 2 twigs tied together. You dress the candle with the oils, light the candle and hold in your left, the cross in your right, say the pray, then let the candle burn out.
Afterwards under no circumstances must you contact the target, otherwise that breaks the spell and the spirit believes the job is done.
If you start to feel the effects of the IS, do some banishing.
