7. Lhabab Duchen
‘Lhabab Duchen’ means the descent of Buddha Shakyamuni from the Tushita Heaven. The twenty-second day of the ninth month of Tibetan calendar (in November), is celebrated as the sacred day of the Buddha's descent from Tushita heaven.
Buddha's mother, Maya Deva, was reborn in Indra's heaven, after her death. To repay her kindness and to liberate her, and also to benefit the gods in the heaven, Buddha ascended to the heaven where he preached before the divine congregation, including his mother, for three months. In celebration of the great occasion of Buddha's descent from Tushita heaven, pujas to pay homage and make offerings to Guru Shakyamuni Buddha and the Sixteen Arhats are usually held. Participating in this auspicious puja brings powerful waves of inspiration and blessings and also it brings merits and help purify obscurations.
