As with any time you are doing meditation, try and arrange to be in a quiet place, free from interruptions. Be physically comfortable (including temperature). Go to the bathroom before starting, turn off your phone.
Whether you are doing this meditation with tea or not, I recommend wearing yellow or other appropriate colours, using an anointing oil if you have one (either the blend from the overview for this week or any sun related oil; sandalwood is always a standard fallback) and anointing your third eye with it (middle of your forehead, essentially; I like to anoint by drawing an equal arm cross inside of a circle). The anointing of the third eye helps to open you up to greater perceptions/wider perceptions, and doing so with the Tifareth related oil will encourage your perspectives in that direction.
