>>40601492 (OP)Hypnosis is a procces of suggesting the mind by reducing the left hemisphere to a semi-sleep state through stimulating the pleasure centers of the brain using relaxing sounds. In this case it wouldn't work, since you need her consent.
Most spells & rituals concerning love or sex attraction works as a placebo effect to shift your mind as also the current of your electromagnetic field, emitting subtle energies that maintained through time becomes materialized in events, situations, persons (this is what we call a causality), thanks to the butterfly effect.
Free will exists because the consciousness of a person only can be modified by itself, meaning the only ways for an specific person to behave as the practitioner wishes it would require for her/him to be spiritually weak/suggestible (most of the cases on these days).
In conclusion, you don't need any special technique, spell or ritual, just intend it with your mind, align with it, use a correct use of your energy then it should have an external response of your objetive, specially if you both share a friendly bond, try to shift it to sexual tension.
