On the second day of Pesach the Jewish people start Sefirat HaOmer (The counting of the Omer) that goes all the way to Shavuot. One of the simple explanations say that people should take advantage of these days to apply one of the forty eight ways of acquiring the Torah each day. At a deeper level the counting of the Omer  is very significant in the kabbalistic meditation world. The Arizal taught three main meditations to done during this time:

1.- Absorption of the blood

2.- Bring abundance into the Sefirot

3.- Sweeten the 320 judgements

It is known that when Adama HaRishon committed the sin many of the spiritual structures got damage. One of the jewish kabbalistic principles is that anything related to judaism is an opportunity to do a “tikun” for the sin of Adam HaRishon. When Adam sinned the nai of ABA was blemished; therefore it was removed from the nai of IMA.  In consequence the nai of IMA became a ribua:  אאהאהיאהיה which has the same gematria of “dam (blood)” that is 44. So, the meditation of “absorbing the blood” consists in bringing back the nai of ABA (י–ה–ו–ה) into the ribua of Ekie. Through the nai of ABA, the nai of IMA will be turned straight into א–ה–י–ה; without ribua. This meditation is should be done every day, of the counting of the Omer, to the Sefira that applies to each day...
