Religious practice

I sometimes wonder if it’s truly necessary to practice religion by regularly visiting temples, rinpoches, or religious ceremonies like nay. Personally, I feel that everything comes down to the state of one’s sem (mind). If our mind is filled with negativity and lacks meaningful intention, then simply engaging in religious rituals may not bring much benefit. In that sense, the essence of religious practice lies in cultivating a positive and genuine mindset. Without that, external practices alone might not hold much value.
