Firstly, we are a Dutch company, registered at the Dutch Chamber of Commerce. That means that a large percentage of the price you pay for the retreat is VAT and other Dutch taxes that we must pay.
Secondly, of course, there are the ongoing costs of the location itself (rent, gas, electricity, water, insurances), plus the repayment of the initial investment needed in order to establish the Acsauhaya center (renovation, creating facilities, furnishing, decoration, construction of the website, etc.). Besides the costs for the location, there are running costs of travel and transportation, food and drinks, and other general operating costs (such as website maintenance, office supplies, accountancy fees, etc.).
Furthermore, there are costs for the ayahuasca and the medicinal plants and costs for getting them here to Europe. Last, but not least, it takes a lot of staff to run a retreat (center). Even though we try to work with volunteers as much as possible (and they do take up a huge part of the work!), you still need professionals in the center as well as in support functions: shamans (who travel here with their families), facilitators, people in construction, website developers, cooks, etc.
