guys who has been meditating for sometime what kinds of spiritual experinces do you have during meditation?

The more you meditate, when done properly, the less "spiritual experiences" you have and the more deepening of insights and spaciousness in both meditation and ordinary waking life. This is goal of meditation practice. In early meditation practice--or depending on the exact type of practice, very many different experiences can be be accessed. Them experienced meditator has a better grasp of what causes these experiences and what they mean than the person who is intentionally seeking alternative mind states through trance and meditation.

I'm not sure it a spiritual experience... But, I feel a complete deep relaxation and a oneness with the universe, giving a revitalisation.

I have no spiritual experiences.... it just relaxes tense muscles... mostly in the neck and upper back.

The rosary is an excellent form of meditation.
