-.- Alright, let me clear something up here: Spiritual Pressure (aka, "Reiatsu,") is the visual distortions of Spiritual Power being "Vented" into the atmosphere from the Spiritual body. Since Spiritual Energy can be Empathetically manipulated, you can often feel someone's Resolve when their Spiritual Power flares at a high rate.

Whether that Resolve is filled with bloodlust (When Kenpachi Zaraki's Spiritual Pressure felt like it was shoving a sword through one's chest) or wrath (Yama's Spiritual Pressure causing a Lieutenant to start hyperventilating) or sheer menace (Aizen or Gin have done this) that is the physical and phsychological affects of Spiritual Pressure.

Spiritual Pressure is just ONE of many ways to utilize Spiritual Energy within your body from your overall Spiritual Power. Kidō is a more focused, disciplined way of turning that energy into a weapon, shield, or a cage. Within Zanjutsu, it can augment your attack and defense power. Hakuda can potentially make you swifter, take more damage and deliver more physically. Hohō enhances one's overall speed and physical movement.

You get what I mean? Killing Intent, is a state of mind that emanates through characters, sometimes from the most bloodthirsty and ruthless ones they can actually project it towards people to where they could actually "Feel" it. In regards to using it with Spiritual Energy, Zanpakutō respond to your Resolve, which can also be your Killing Intent, which heightens its effectiveness like an Adrenaline Rush would to the human body.

Make sense?
