During mantra "i" for clairvoyance

Good day Instructors,

I was doing the mentra " I " and after à while, the sound of the insect Cicada in summer came to me. I was wondering if they are strong élémentals? Similar to the cricket? Do they have any corolation to the pituitary or pinial gland? The cicada is a close to heart sound that i have cherish since childhood. Guess I was just wondering what type of animals they are. Further my méditation.

Thank you
