I just want to make 2 suggestions (observations) that you might choose to reflect upon:
1.) Seeking an advance apology for incomplete presence is OK. But try replacing it with the intention of requesting your focused presence from the Divine & Gurus. Think what u wanna create & see the magic happen - subconscious conditioning (U r subconsciously allowing urself to be OK with this as you acknowledge the forgiveness for the same).
2.) I am not able to recall the source but during my learning days of Reiki & Pranuc healing followed by self study on various healing techniques, I came across the logical explanation of taking a bath. It is not at all necessary to hv taken a bath before meditating. The simple fundamental (that all religious scriptures recommend too) is that a bath helps open up all ur senses & helps in developing rha faith of having a cleansed auric field. Likewise, in healings, the recepients are suggested to avoid taking a shower for the next 2-4 hours after the healing, for the simple reason that the aura that has absorbed the healing vibes will get affected by shower. So, if u take bath & then meditate, you simply have a better probability of maintaining a vibrant aura through the day. This one was the best logic I related to the significance of bath.
