One of the best ways to experience the effects of meditation is to attend a weekend retreat. The whole experience of meditating with a group and getting personal guidance from an experienced teacher can make a big difference in how fast one moves ahead in the path of meditation.
It is also important to spend a night or two in a place vibrated by many minds that meditate together.
If you ever have the opportunity make sure to attend a weekend meditation retreat.
I always make an effort to organize or participate in these events as often as I can and I still feel that it makes a difference.
