Depends on the path You follow how and when will You gain abilities.
I myself, for example consider forcing spiritual development through means such as mentioned ( and honestly overused ) mediation to be bit...vulgar, profane If You will. If You practice regularly, cast spells, respect Your deity/ies, learn etc, You will gain abilities in time. More important, in proper time.
Occultists ( such as Rosecrucians for example ) believe that each spirit ( read soul ) has a single talent ( ability, power ) which is consistent with general mental nature of the spirit ( read soul again ) and that others appear as "gifts" from higher spirits.
Simply put, walk the spiritual path with knowledge and revrance, and let abilities be gained and earned.
To boost and fasten the process ( If You really want to ) use things like "Power oil", "Master key" , sleep with some of the Solomon seals and Anise seeds uncer pillow etc.
Blessings and good luck
