1And so too is it with buying and selling, and the profit and wealth of a person. For in truth the main true profit of a person is drawn by bringing up sparks from the husks and bringing them into holiness by way of doing the buying and selling with complete faith, giving much charity and having intention during the time of buying and selling that he profit in order that he should give charity to those involved with true service to God. As they are included in the Head of the House (the righteous man of the generation), as mentioned above. And therefore sometimes the profit appears before his eyes and it appears to him that he has already made the profit; but before the complete conclusion of the deal, everything is reversed because of some small action and he makes no profit. And sometimes he even loses the principle (the original investment). And all this is the aspect mentioned above. For that which he began to profit is the aspect of bringing in the profit to the courtyard, but it is still not brought into the aspect of the House, which is the essence of the protection of wealth, as mentioned above. But before he brings it into the House, he must first separate the [holy] sparks from the depths of the husks. And sometimes he does not have the strength for this and the husks attach themselves to him, so he loses everything, as mentioned above. Hence the main rectification for this is charity to fitting poor people, as mentioned above. As the essential separation of the sparks from the depths of the husks is by way of charity, in the aspect of, 'charity saves from death.' For charity saves and elevates the sparks from the husks, which are the side of death - the aspect of, 'her feet go down to death.' Feet are the aspect of money, etc. - but by way of charity, they are raised from there. (This is as it is all brought by our master, our teacher and our rabbi [Rebbe Nachman] in a different place.) And so it is exact, he should merit to bring the wealth inside into the House so that it will be preserved in his hands, and as mentioned above.
