The purpose of learning geometry is not the knowledge of shape, but learning the construction of shape. In constructing shapes, knowledge emerges. It is in the same way that wisdom emerges from the temple: understanding shape permits understanding relationships, and this is the means to application. The sacred act of such geometry reveals what was perceived but not known: what is defined can be related, and such relation produces the conditions for what is desired. This is the way and reason for which an altar is constructed through geometry.
As one might become disgusted with life after their friend or spouse dies, discontinuing the fire ritual, or failing to maintain the fire, as a fire may be permitted to extinguish itself, so does that which sustains life bring an end to it.
Those who have sacrificed their fluids to Indra find that the fire knows no difference between blood and water. The ashes of wood, grass, flesh, even fluid are the same. What difference is there between the ashes of blood, saliva, mucus, bile, semen or any of the other liquids in the body when the water common in them all is removed? This is how by sacrifice one understands a great deal of impurity can be tolerated by Agni, how Agni takes what is pure, leaving behind what is not. Discover the limits of your own tolerance for impurity: it is not by wearing the sacred thread that one becomes a Brahaman, but by satisfying the conditions of confidence in your sacrifice. it is good enough.
How can one injure another when seeking for Brahma, in Brahmacharya? Even if one seeks Brahma upon the battle's field, you will not harm another, and in such harmlessness, succeed. Fast even unto your death, enter into the purifying waters until you drown: you will not destroy yourself. All limits or extremity are illusionary, yet there is nevertheless Brahma. Seek this Brahma not in the extremities, but in the exertion of the seeking. Then you will find Brahma in the sufficiency of your moderation and self-restraint, in the limits of reality. Indeed, one who collapses on their journey fails in it, but the one who takes it in stages (Ashramas) succeeds - and returns home.
Sages wear no distinguishing marks, and yet conduct themselves sensibly. Proclaim sufficiency! All you do teaches, speaks, tells of sufficiency! A child is born without clothes, as if unaffected by heat or cold, pleasure or pain, incapable of accepting anything. And yet this child will take up the wearing of clothing, even ceremonial clothing, only to discard it later. You are well-established in the path, incapable of avoiding the stages of your journey. By merely sustaining your life, you succeed.
Do you think Atman is in every being? Bow before all beings and you will soon give up that thought. Sacrifice that belief, and all others. Having bowed to every being, you will no longer bow before anyone. Nor tolerate any bowing before you. You neither require nor deserve to be bowed to.
