"Attachment figures are targets of proximity maintenance. Humans of all ages tend to seek and enjoy proximity to their attachment figures in times of need and to experience distress upon separation from them."

How is therapy congruent with the above basic human need that Bowlby identified?

Therapy that promotes attachment to the therapist as a means for healing, is at direct odds with the very attachment theory from which it sprang, because its structure is such that proximity maintenance is blocked and separation distress is assured.
