First, the three main postures shall be considered since at every moment we are assuming one of them, that is, the standing, seated and lying down posture. We got so much used to pass from one to another posture, or to remain for hours in certain posture, that we have lost any critical sense to notice if our present posture is correct or not.
Renunciation leads naturally to contemplation. One cannot define Renunciation itself. There is void between perfect state and ascetic state, and a continuous Renunciation of the soul should fill this void.
In this posture, the weight of the body remains evenly distributed on both legs. Feet remain parallel and somewhat apart (20 to 30 centimeters). The trunk remains naturally upright, arms pending freely at both sides and head supported by the least possible effort from the neck.
In the beginning of his path, the soul is too much busy with his troubles and sorrows, and that is why worldly evils are to him just a mere consideration to which he sticks by attachment or sympathy.
Esta postura es similar a la vegetativa pero en la misma los talones deben juntarse y las puntas de los pies se mantienen algo separadas. Las manos se pueden enganchar la una en la otra delante del cuerpo manteniéndose sueltos los brazos.
“My soul is tied to all souls forever. Just as God is a prisoner in the Creation, so my soul is a prisoner of its love to all souls. These souls are my life; and I am these souls.
Most likely, our ordinary seated posture is a legacy from the ancient Egyptians, who exalted and perfected it to the utmost. The cultural level of a people, or of an individual, is proportional to his concern for perfecting little daily habits.
You talk, you think and you feel always in dualistic terms, and life is unity. You should not understand this unity as only one thing, but as an organic totality, indivisible and simple in itself, and composed as attribute.
The fundamental difference between vegetative posture seated and mental posture is again its reduced support point. In fact, heels are together in this position; so, knees come close and even can join together.
Simple knowledge is a state of unity and similarity between subject and object. This unity cannot be achieved through an active state of your mind, which is always dual. Knowledge or rational understanding is dual always.
