This is why, one cannot presume upon seeing the acts of major renunciation or partial renunciation that the renunciant has reached the requisite stage of spiritual purity.
The importance of formal routines and rituals lies in the fact that once the required stage of spiritual purity is attained, the routines and activities ensure that the stage of spiritual development of the soul is not squandered. For instance, it may be possible for a person who has partial renunciation that he may reap the spiritual benefits of one who has taken the complete renunciation. But it is not possible to sustain that spiritual benefit without taking up the vows of complete renunciation oneself. (To maintain bhaava one must maintain kriyaa also)
Thus, one should make focussed efforts (purushaartha) to attain samyaktva, to understand fully the extreme difficulties in attaining and knowing all the modalities associated with samyaktva.
