(c) Rabbi Menachem Creditor
Nefesh HaChayim (1:3): God created and granted human with beings with enormous power over the universe, with cosmic consequences corresponding to every deed, word, and thought, be it for good or the opposite, God forbid.
For in a person's positive deeds speech and thoughts, she sustains and adds power to revealed and hidden dimensions of the universe, as it is written "And I have placed my words in your mouth… to plant the heavens and make firm the earth. (Is. 51:16)" And as the sages of blessed memory said, "Do not read 'my children' rather 'my builders' (TB Ber. 64a)" for people, God's children, build and strengthen the dimensions of the universe.
The reverse is also true, God forbid. Through a person's deeds, words, and thoughts which are not positive, considerable powers, and inestimable dimensions of the universe are destroyed, as it is said, "Your ravager and your ruiner from you manifested. (Is. 49:17)."
Comment: Stanley Martin Lieber (aka Stan Lee) taught, "With great power comes great responsibility."1 The inherent power every person wields should never be underestimated. No act is neutral, not even inaction, for an agent of divine energy. Deeds matter, words matter - thoughts matter! Whereas Jewish tradition has long held that emotions cannot be commanded, and that intentions do not carry legal consequence2, it is also true that our thoughts truly impact the world.
