Agastya (the star Canopus, second brightest in the night sky, but invisible from much of the northern hemisphere) is associated in Vedic tradition with the sage Agastya, credited with bringing Vedic culture to South India. Each year it disappears into the Sun's glare (Asta) and later reappears (Udaya, or Darshan), a marker long used to anchor parts of the ritual calendar, most notably the timing of Upakarma observances.

Significance
What the Tradition Says
Upakarma Timing
Agastya's heliacal rising is one of the traditional markers used alongside Shravana Nakshatra and other criteria for placing Yajur/Rigveda Upakarma within its correct window.
Scientific Basis
These dates are computed from the real astronomical positions of Canopus and the Sun for each year, not a fixed calendar date.
Latitude Dependence
Canopus's visibility depends strongly on latitude, and it never rises at all north of roughly the mid-latitudes.

Legends
Three Stories of Maharshi Agastya
The Bowing of the Vindhya Mountain
According to legend, the Vindhya mountain once grew so proud of its height that it blocked the Sun's path, cutting off sunlight from reaching South India. At the request of the gods and sages, Sage Agastya asked the Vindhya mountain for permission to travel south past it. Out of respect, the Vindhya mountain bowed down. Sage Agastya then instructed it to remain bowed until he returned. Maharshi Agastya never returned north, and for this reason the Vindhya range remains in its lowered, restrained form to this day.
The Legend of Drinking the Ocean
In another well-known story, the army of the demon Vritrasura had hidden in the ocean, troubling the gods. The gods sought help from Lord Vishnu, who directed them to Sage Agastya. Through the power of his mantra, Agastya drank the entire ocean in a single handful, making it possible to destroy the demons. This story carries a deep astronomical and symbolic meaning: ancient sages understood it as a metaphor for the evaporation that accompanies the rising of the star Agastya. When this star rises, the rains generally end and evaporation from the ocean intensifies, so Sage Agastya's drinking of the ocean is a divine, spiritual expression of a real natural phenomenon.
Marriage to Lopamudra
Maharshi Agastya married Lopamudra, the learned and Veda-versed princess of the Vidarbha kingdom. Their marriage is regarded as a symbol of the ideal balance between householder life and spiritual life. Lopamudra herself, immersed in her husband's wisdom and love, composed Vedic hymns (richas) of her own. Together, the couple are presented as an ideal pair, who also guided Lord Rama and Sita during their years in exile.
Scripture
Agastya Arghya Mantras from the Puranas and Astrological Texts
"Agastya, digging with his spade, desires progeny, offspring, and strength. This powerful sage nourishes both varnas and has received true blessings among the gods."
"You shine like the kaash flower, born of fire and wind, son of Mitra and Varuna, born from a pot (Kumbhayoni), who checked the growing height of the Vindhya, who removes the impurity of the clouds' waters. O beloved of gems, lord among gods, dweller of Lanka, salutations to you."
Visarjan Mantra for Lopamudra
राजपुत्रि महाभागे ऋषिपत्नि वरानने॥
लोपामुद्रे नमस्तुभ्यमर्घ्य मे प्रतिगृह्यताम्।
"O royal princess, greatly fortunate one, wife of the sage, Lopamudra of beautiful countenance, may you accept my offering of Arghya."
