Speak the Truth
Do not be careless about truth,
Do not be careless about what is right
Do not be careless about welfare
Do not be careless about propriety
Do not neglect your duties to the Gods and ancestors
Let your mother be God to you
Let your father be God to you
Let your teacher be God to you
Let a guest be God to you
Perform only deeds to which no blame attaches, no other
Respect such deed of ours as have been well done no other
This is the rule, this the teaching, this is the instruction
of the Veda –
And so it should be respected
Of course law have I spoken
Of truth have I spoken
Taittiriya Upanishad
