Question: Can we perform any action in order to bestow now?
Answer: It can be done at any moment if you rise to the height of that action. But we advance towards it gradually; first I am ready to bestow upon others 1%, and then 2%, and then 3% and so on until I reach 100%.
When I am ready to bestow upon them 1%, it means that I want 99% for myself! And if I want to bestow upon them 2%, it means that I want 98% for myself! And so I gradually rise towards bestowal, towards Lishma (for His sake).
This is called the time of preparation; it lasts until my intention becomes 100% for bestowal. So far, this 100% of intention extends into one gram of pleasure, one portion of Light, one quantum of Light. Then I intensify my intention so that it will be enough for two portions of Light and then three portions, until I can restrain myself from receiving all the incoming Light, which means I am building myself a Masach (screen) of Bina, to bestow in order to bestow. After attaining this level I can even receive in order to bestow, after having developed the right Masach.
