Yes, this is true. But many temples have distracting elements like the noise from the bells and so on. The attendants might ask us to leave when it's time for Nivedhyam. So it's nice to sit for dhyana but we need to be prepared for distractions also.
The attainment of one-pointedness of the mind and senses is the best of practices—superior to all.
—Sri Shankaracharya, A Thousand Teachings, 8th century
There are umpteen number of solutions to overcome the distractions. There are tips and what is needed is iron will to practice yoga, the meditation, concentration, etc The alleged distractions will gradually pass. It is more about conquering the mind.
And in Hinduism, worshiping God through music is a gift. There was Meerabai. Devotees perform Bhajans and try to bring out a total Krishna consciousness which was responsible in molding the path of total devotion.
We had Saint Tyagaraja who was immersed into devotion to Sri Rama and reported to have composed thousands of Kritis… and we had now only 700 praising the God.
And there is vittal bhajans chanting the names of Sri Panduranga… reciting the names of Sri Sai, etc etc It is form of worship going near to God governed by state of mind and belief.
One mans elixir is other mans poison....while few consider noise of Bell as source of distraction, there may be few who consider ringing of bell as an auspicious sound with positive vibe..
Every Church has a Bell... and even in Buddhism Bells used during prayers.
While for a few, the sound of bell is considered as a source of distraction.... there are people who believe that it has rhythm and love to hear the sound.
