Second: with the help of a water jug and a cup (that has the same water capacity from the one each adolescent holds), the spiritist teacher should place water in his/her cup and then transfer it to each individual plastic bag that was given to each adolescent. Please place the water inside the individual plastic bags on the same water level that would be equivalent to the level ‘INTEGRAL BEING’.

         Third: offer/suggest to the youth group to place a substance that colours the water (for example, ink gouache). If they agree, the spiritist teacher will assist them doing this. As soon as this is done, they should tie a knot in their plastic bags.

         Fourth: give the adolescent thirty seconds to transfer the water from their plastic bags into their cups; the ones that were handed over by the spiritist teacher to each of them (the one with stripes).

         Note: please leave some objects (such as scissors, tooth pick, pencils or other pointed objects) within reach of the young group, so they can burst the plastic bag if they want to.

         Fifth: once the stipulated time is up, the spiritist teacher should observe the results obtained. Through dialogue, he/she will begin discussing each step of the experiment with the young people; i.e., giving the following definitions:

         - The labelled cup and the empty plastic bag represent: the physical body.
         – The coloured substance represents: impurities (imperfections).
         – The water represents: our perispirit.
         - The ones who facilitated the exchange of water from the plastic bag to the cup represent: short cuts found from the work that needs to be done, through knowledge and practice of good.

         Note A: These conclusions should preferably be given by the youth group, through inquiries made by the spiritist teacher.

         Note B: The best option would be to open the bag and then transfer the water to the cup. The water placed inside the containers (plastic bag and cup that represented the physical body) is merely illustrative, since the perispirit is not enclosed within the limits of the physical body.

         Conclusion: every positive attitude towards life and work in goodness will become part of our perispiritual file.

         Nota A: To facilitate the understanding of such interesting and complex subject it’s important that the spiritist teacher has some definitions in mind that will help him/her talk about the matter to the adolescents:
         - Universe: A collection of everything that exists; including the Earth, stars, galaxies and all matter that exists in space.
         - To condense: to become dense or compact, to become thicker; to abridge, to abbreviate; to concentrate.
         - Fluid: gaseous or liquid substance; takes the shape of the container in which it is placed.
         - Ethereal: heavenly, celestial, aerial, sublime, immaterial, intangible, pure.
         - Imponderable: not capable of being weighed or evaluated.
         - Quintessence: the highest degree, the peak, exquisite, refined.
         - Cosmo: Universe.
         - Tangible: that can be touched; sensitive.

         Nota B: the terms INTEGRAL BEING, INTERMEDIATE BEING and NON-INTEGRAL BEING were used to highlight the process of mutilation (or non- mutilation) of the perispirit. These terms haven’t been used with the intention to say that the integral being would be a perfect being. These expressions can be replaced by other expressions the spiritist teacher feels are more adequate.
