Background for question: "One who is versed in kabbala knows how to act at the right time by knowing which sefira dominates at a particular time, and he cleaves to the light of the dominant sefira. He can then bring about the correct adjustment and harmonization of the sefirot through proper thought, speech and deed. In this way a person extricates himself from lack of awareness of G-d, which may be compared to sleep and death, and binds himself to holiness and eternal life, which is the mystery of Gan Eden. Thus the Crown of the Shechina never departs from his head.
[Translation and commentary by Moshe Miller from Tomer Devorah chap. 10.]"
My question: I seek to further understand this issue and have in this respect the following questions: What is the correct way to use the sefirotic dominance in daily life? Should one for example focus on acts of kindness on sundays (since chesed is in "control"), or are we to make special yichudim of divine names in accordance with the ruling sefira for a particular time?
