Is there a ritual for cutting ties?

Yes there are several rituals this is the one I have used and recommend.

It is done through visualisation and can be performed as much as necessary in the passing of time, you will find you wont feel you have the need to do it.

Visualise you are standing opposite the one you wish to cut ties with

And visualise a ribbon of each associated colour with each chakra for example red for base, orange for sacral, yellow for solar plexus, green or pink for the heart, blue for throat, indigo for third eye and purple for crown. These coloured ribbons join each of you together.

As you face one another smile and send love. at the same time visualise a pink cloud surrounding both you feet, pink is associated with love.

Now visualise a pair of ornate golden scissors cutting each ribbon in turn starting at the base chakra, as you cut each ribbon each end curls back to each person and at the same time the pink cloud rises up to obscure the other.

All the time smiling and sending them love to see them on their way. Gradually as you cut you will obscure the person you are cutting ties with and with the final tie complete you have sent them away with love to live their own life and yours.

You will have to do this a few times and every time you think of them do this visualisation, You will notice as time passes you wont think of them so much and you will be able to do the ritual quicker and easier and it will no longer hurt if your thoughts do turn to the person you are cutting ties with.

Do not do this ritual after a bereavement or when you are in an actual relationship with someone. It should only be used when the relationship is over and no longer serves a purpose. To allow you both to move on, one neither hating the other, that is why you smile and send love as you send them on their way.
