Did jesus tell his disciples about the holy spirit yes or no?

The Holy Spirit IS Jesus and God. ( the trinity ) After Jesus was resurrected, God sent the Holy Spirit down to Earth so that we may have a relationship with him again.

Another Answer:

The power that sustains all things emanates from the current God Family - Father and Son - and can come into all who follow Jesus - this is their Holy Spirit:

Romans 8:9New King James Version (NKJV)

9 But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His.
