how to reach to Shiva's abode.

 

as in puranas - 

While worshipping the Shiva Linga, the mantra OM NAMAH SHIVAY should be continuously chanted.

Chanting this mantra for five crore times, helps a man in attaining to the abode of Shiva. Worship of

Shiva done during the mid night is considered to be especially fructifying.
