- "Live long and prosper." - T'Shael.

Spock demonstrates the ta'al.
The Ta'al was the traditional Vulcan salute that was given when greeting another.
In 2283, after encountering a group of seemingly atheletic members of the Klarshameth, T'Shael greeted them with the ta'al gesture. (TOS novel: Dwellers in the Crucible)
