Magic is literal but in the case of sacrafice involving virgins two young pigeons [less than breeding age] will suffice.
Get yourself a copy of the book ''the secret lore of magic'' by the author highlighted in my signature below and he'll maybe awaken the intuition in you. Can't guarantee that though, you'd have to be on the right path to begin with, if you know what i mean.
If you are meant to have it i'm sure you will.
Now, to use one of your own words ''Caution'' or you could end up like that poor woman in the opening post or worse should you evoke the wrath of the supernatural.
In freemasonry [who i believe practice old drui ritual to their own ends] a penalty for talking out of class, departing secrets and so on was to cut out the tongue, bury it at the ebb of the tide and then hang you by the neck.
In fact, you have to do this yourself less you be judged on your deed on the stairway to the afterlife.
There's always that price to pay in life and death is'nt there? And so many variant punishments/consequence dictated by authorities overt and covert.
What will they come up with next?
Everything has its price? I don't know about that. I think somethings freely given can be abused and that can give rise to problems.
Whatever they come up with next will not or had better not involve me.

As a self confessed ''learner'' take it from a guy who knows alot about the ''old ways'' that things have changed since then in that some rituals can't be performed anymore as, however good your intent, demonic underworld entities pollute the grove turning it from Seelie [good] to unseelie [evil]
Planting geranium is one thing, progress up the higher ritual rungs of the ladder requires the oath and with or without that there are consequences if you venture were you should'nt be.
I doubt you would be even slightly interested in how to control underworld entities so you've little to worry about.
Would'nt have been so long ago you'd be jailed, burned at the stake or dunked for planting round hill forts so whatever you feel you have been ''freely given'' did have a consequence and probably still does if mentioned in the wrong place.,
