If you're referring to Renji, he had already gone through the necessary training to achieve his Bankai; Zabimaru simply withheld its true power because he felt Renji wasn't ready. If it were as easy as the spirit telling its master how to perform it, half the Shinigami in Soul Society would know Bankai. It's nowhere near that simple.
