Generally speaking, when people are active, this gives rise to heat; when people sit quietly, this gives rise to cold. When one is cold, if one moves about this will again produce heat. When one is hot, if one sits still this will again produce coldness. In other words, cold and heat do not depend on the weather but on the person.
What I realize as I observe this is the Tao of taking over the creativity of yin and yang. That which is strong is associated with yang, that which is yielding is associated with yin. If one is strong but not aggressive, humbly lowering oneself, then one will not be irritable but will be peaceful, and equanimous. If one is yielding but not weak, deliberate in action, then one will not be ineffective but will ascend to high illumination.
Able to be strong, able to yield, according with truth and with the time, knowing when to advance and when to withdraw, able to be great and able to be small, able to stop and able to step down, able to be passive and able to be active, one can thereby take over Creation, turn around life and death, reverse the mechanism of energy, leave death and go to life. This is like activity producing heat and quiet sitting producing cold; human power can reverse nature.
Awakening to the Tao Liu I-Ming translated by Thomas Cleary
I am eternally present.
There is nothing to do.
Nowhere to go.
Krishnamurti saw meditation as a great art, “perhaps the greatest.” One must learn this art by practicing without technique—watching oneself: in daily activities (walking, eating), practices (speech, gossip), reactive emotions (hate, jealousy)—becoming aware of these things “without any choice.” Many forms of meditation have been invented to escape conflicts. These forms, according to Krishnamurti are “based on desire… the urge for achievement,” implying conflict, and a “struggle to arrive.” This striving, he saw as “within the limits of a conditioned mind, and in this there is no freedom.” True meditation is “the ending of thought,” leading to “a different dimension… beyond time.” Thought and feeling “dissipate energy.” Their repetition is mechanical, and, while necessary, do not permit one to enter the “immensity of life.” Meditation is the “emptying of the mind of the known.” It is not thought, nor prayer, nor “the self-effacing hypnotism of words, images, hopes and vanities” all of which must “come to an end, easily, without effort and choice, in the flame of awareness.”

Bai Yuzhan said, “The path of inner refinement is extremely simple and easy; just get the fire of the heart to descend into the elixir field. The elixir field is the chamber of water, while the heart is fire. When fire enters water, then water and fire mix and true yang is produced. Therefore people Call them heart and genitals, not water and fire.”
