When I was 14 years old I began to meditate; although, I had no idea what meditation was. At that time, I was a Christian and zealously fixed my mind on what I believed to be God's ever presentness, also, I remained in loving-kindness and expressed it towards all things. This brought me into peace and bliss, which lasted a good nine months straight.
At the time, I didn't know I was even practicing meditation. I always thought God came to me in a special way, and that was why I experienced such peace and bliss. After time, the bliss faded away, as my zeal and energy to focus on God's ever presentness and loving-kindness faded. I thought that I had sinned in some way, which caused God's presence to withdraw from me, and I always longed for that bliss and peace to return. I felt I somehow had to return to God in order to partake of this joy again.
Now, I'm 32 and no longer a Christian, and I understand my experience better. I see that Buddhism explains very well why I had bliss. The peace and bliss was the result of accepting things as they are, remaining fixed in the present moment, and remaining in loving-kindness. I see now that it wasn't the presence of a partiular God, but the result of the meditation practice I unknowingly practiced.
Now, that I see the way into this peace and higher state of being, I find the zeal to take up such a diligent practice lacking. Is there any practice or way to rekindle the zeal that drives one into the higher way?
