“שָׁמְרָה נַפְשִׁי, כִּי-חָסִיד אָנִי”
“Keep my soul, for I am (אָנִי) godly (Chassid);”
The Zohar refers to this verse again, to teach us the relation between the protection of the soul, Chessed and the word אָנִי (I am). The connection is with the name of God in the level of Malchut ADNY אדני . Normally the name reflects the judgment aspect of Malchut דינא . When the letter ד is taken out with the connection to YHVH, that is Chessed. We unite right (Chessed)and left (Gevurah) to form the central column and balance. When they come together we form the combined name of יאהדונהי.
This is the secret of saying the name ADNY (Adonay) when reading the name YHVH יהוה. Having the YHVH name in front of our eyes and in our consciousness when saying the name as ADNY, draws Chessed to our lives.
When we say Amen אמן we create the same effect of drawing light of Chessed to Gevurah and remove judgments.
The letters אני form one of the 72 names. It is placed in Position 37 that is the middle of the chart. The last letter of the name before it (position 36) is ד . Together they form the name אדני but the separated ד gives it balance.
