$this->getLayout->getBlock('myBlock') return false

[ghost]

I can't get block from layout

Layout for Page customer dashboard:

<customer_account_index>
    <turpentine_cache_flag value="0" />
</customer_account_index>

in my template file, I have a statement:

$myBlock = $this->getLayout->getBlock('myBlock'); // $myBlock: false;
$links = $myBlock->getLinks(); // (!) Fatal error: Call to a member function getLinks() on boolean
