WE will conclude our work by laying down certain practical rules which result from the facts and the principles that have been explained in its course. Since man can raise himself to the range of a superhuman being only when his soul has acquired the necessary degree of purification in this life, it is evidently his interest to apply himself to the culture of his soul, to preserve it from every stain, to keep it from falling. Be good, generous, and compassionate; grateful for benefits, accessible to the suffering, the friend of the oppressed. Console those who suffer and who weep. Practise every form of charity. Endeavour to raise your thoughts above terrestrial things. Strive against those material instincts, which are the stigmata of human existence. Aspire to the good and the beautiful. Live in the most elevated spheres, those which are the least bound to lower things. It is only thus that you can elevate and ennoble your soul, and render it fit to enjoy the higher existence which awaits it in the ethereal spheres. For, if your soul be vicious and corrupt, if, during all your terrestrial life, you have been sunk in material interests, exclusively given up to purely physical occupations and enjoyments, which make you the fellow of the animals; if your heart has been hard, your conscience dumb, your instincts low and evil, you will be condemned to recommence a second existence on the earth. Once, or many times again you will have to bear the burthen of life on this disinherited globe, where physical suffering and moral evil have taken up their abode, where happiness is unknown, and unhappiness is the universal law. There is another motive for our careful cultivation of the faculties of the soul, and for our constantly purifying ourselves by the practice of good. Noble and generous persons, elect souls, are, as we have said, the only ones capable of communicating with the dead, with the beloved beings whom they have lost. If, therefore, we be stained with moral evil, we shall not receive any communication, any succour from the beings who have left us, and whom we loved. This is a powerful motive for our constant striving towards perfection.
