We train our minds to help us understand the thought patterns that operate out of impulse and desire, controlled by causes and conditions. You have to see it yourself. Start at the surface; sit down, hold still, and watch what you cannot prevent from moving. Look more and more deeply into whatever is arising and the space within which it occurs. It’s not a deeper training, particularly – that’s relative. The actual depth won’t seem like relative depth. We have to use words like suchness to even talk about it.
