Buddha Tönpa Shenrab teaching subjects such as medicine, divination, astrology, and ritual

Tönpa Shenrap began the spread of the Yungdrung Bön by first giving teachings related to cosmogony and cosmology to two of his primary disciples, Malo and Yalo, to bodhisattvas who had descended from heaven to receive the teachings, and to many other powerful, worldly deities.  Then to the gods of Mt. Meru and other deities, he taught powerful methods for subduing negative forces.  Traveling to the city of Langling, he taught from the 100,000 verses of Perfecting.  In Olmo Lungring, countless human and non-human beings gathered including those who were to be lineage holders.  To this assembly, he taught the Nine Ways of Bön.

More specifically, it is said that on the 30th day of the lunar month, that Buddha Tönpa Shenrab taught the beings of the formless realm.

On the 1st of the lunar month, He taught the gods who reside in space in the highest realm.

On the 8th of the lunar month, He taught the clear-light gods.

On the 13th of the lunar month, He taught the tsangri gods.

On the 14th of the lunar month, He taught the gods of the form realm.

On the 15th of the lunar month, He taught on Mt. Meru to the gods of the desire realm.

On the 16th of the month, He taught the gods of Gyalchen Rikshe.

On the 22nd of the lunar month, He taught the demi-gods.

On the 29th of the lunar month, He taught the lü (sanskrit: naga) of the desire realm.

Therefore, these days are significant in the Yungdrung Bön lunar calendar.
