Knowledge, Meditation, Devotion, & Action
Whether you are a dhyan yogi, karmi, or bhakta, you will have to utilize jnana.  As Sri Krishna says:

Na hi jnanena sadrsham pavitram iha vidyate
tat svayam yogasamsiddhah kalen'atmani vindati

Verily there is no purifier in this world like knowledge.
The one perfected in Yoga realizes that fact within in due time.
[dhyan = meditation, karmi = one who follows the path of selfless action; bhakta = one who follows the path of devotion; jnana = Knowledge that discerns between the Eternal and the noneternal]

Meditation and devotion will have to bow to karma.  That is, one will have to test one's realization of both in the field of action.  But action must be performed only after knowledge, jnanam, is present.  All hail King Jnanam, then!  King Prema and Queen Bhakti can only assume the throne after He has established His reign.
