Many cultures believe that there are colors associated with each day of the week. And each day of the week is associated either with a planet or with a deity. Jupiter, the planet of abundance and luck, rules Thursday. This is the planet of goodness and generosity; thus, acts of service and donating your time are considered auspicious on Thursdays.
Since Jupiter is the ruling planet of Thursday, it signifies wisdom, intelligence, teaching, muscular body, pious place, philosophical outlook, teacher, wealth.
Wearing yellow or off-white clothes, keeping yellow or off-white flowers at home and eating arhar dal, papaya and rice with ghee on Thursdays may bring in good results.
Yellow is the color of knowledge and learning. It symbolizes happiness, peace, meditation, competence and mental development. It is the color of spring and activates the mind. Lord Vishnu’s dress is yellow symbolizing his representation of knowledge. Lord Krishna and Ganesha also wear yellow dresses. Yellow clothes are worn and yellow food is eaten at spring festivals.
Thursday is the best day in the week to begin any educational efforts and ventures, being the ideal day to show your gratitude to our teachers and all those from whom we learn or gain knowledge in some way or the other. It is the most auspicious day to visit temples and receive divine blessings.
