Fasting is considered a powerful remedy in astrology for overcoming obstacles and improving various aspects of life. By fasting according to our birth chart, we can utilize this practice to its full potential.

If a planet is unfavorable in our birth chart, fasting regularly on the days ruled by that planet can help. For example, fasting on Sunday for the Sun, Monday for the Moon, Tuesday for Mars, Wednesday for Mercury, Thursday for Jupiter, Friday for Venus, and Saturday for Saturn.

The Align27 app can automatically calculate the days to fast based on an individual's birth chart and other personalized daily rituals.

During fasting, the digestive energy or agni in the body changes according to the planet ruling the day. By consuming less food, we reduce the amount of planetary energy rising within us.

Fasting, known as "vrat" in Sanskrit, refers to self-imposed restrictions. Through fasting, we strengthen our mind against temptation and improve our ability to resist it.

Astrologically, fasting serves as a remedy for the 12th house, which represents loss. It can also be beneficial for relationships, as fasting on days associated with a planet ruling the sign of an individual's Upapada, which signifies relationships, can help combat relationship issues.

The Align27 app provides information on the days to fast according to an individual's birth chart and other generic planetary periods.

Fasting can also serve as a tool for spiritual progress through the practice of Niyama, one of the eight limbs of the spiritual path outlined in Patanjali's Yoga Sutras. Fasting can lead to inner purity, gratitude, contentment, self-discipline, self-study, and surrender.

There are several important days to fast, such as Mahashivratri, Navratri, Full Moon, New Moon, and Ekadashi. Fasting during these periods can help purify the mind and body and make it easier to meditate and pray.

Overall, fasting is a powerful tool that can improve various aspects of life when used appropriately and in conjunction with astrology and spiritual practices.
