לקוטי שיחות חלק לח - חג השבועות

A. Writings from Achronim discuss the order of festivals and customs on Shavuos. From the Gemara we learn about seven days leading to Shavuos and the significant intermediary steps. Noteworthy is the discussion on changing clothing for honor and purity. The day follows from divine counting starting with Sefiras HaOmer.

B. The preparation for Shavuos involves internalizing the unity which was necessary for receiving the Torah. This is derived from the fact that it was given to a 'unified nation'. Furthermore, specific customs and practices are highlighted, adding depth to each observance.

C. When accepting Torah on Shavuos it impacts each day thereafter—requiring constant refinement in mitzvos and attitudes toward them.

The lessons from receiving Torah instruct on patience, refinement, and moral elevation to reach ultimate spiritual height.
