For One hr Meditation ... every sound of Bell gives a sweet reminder that you are the bamboo of Flute and sound is divine .
Sit or lay down as per comfort choice is yours , calm your mind , centralize your thought towards Heart , that is your bhava-chakra also .Try to keep rooted yourself from Earthy Ground
( you are not body , you are not scenes , your not as wordily eyes see you , you can not catch from wordily aspects , you are Soul Pure Soul), every bell is gentle reminder to yourself to very Inner being , that's what you are ! use the method of neti neti during meditation . and be rooted .
