In page 116 of the Lemuria Scrolls, Gurudeva states this:
Knowledge of sound formed a singular science in those early days. It was known then what has been forgotten now, that everything has a sound, that even emotions create sounds that are “heard” by others. All through the Dvapara Yuga, devas of the inner worlds served and helped the inhabitants of this planet through birds. If one were ill, he could go into the forest and by concentrating and riding awareness in on the tones of singing birds, the physical body would be healed. Meditation was performed for practical reasons, not only for Self Realization, which was of the the utmost importance. Meditation drew one closer to the satguru’s mind and invoked the help of beings behind the veil between the two worlds. Meditation was pursued for healing, arts, culture and myriad other sciences of that day. Aum.

Our Friend, The Regal Peacock
It is the peacock, our largest of birds, the most intelligent of all, that warns and protects our monasteries from all intrusions of the other developing species of animals that eat other animals. Through thought transference we speak to the peacock and understand his sounds and make sounds like his to him. At this time we a happy balance between the animal world and the human world. But we are told that during the Kali Yuga these two worlds will pull far apart and be unable to communicate with or know each other, so great is the darkness of that time.

What is Sivatri and the Nature of Nirvikalpa Samadhi
Mahasivaratri: A time of striving to realize Parasiva. In our teachings yoga is the restraint of mental activity (chitta vritti). Nivritti marga-the path of renunciation. Pravritti marga-the path of action or life in worldly society. Ashrama dharma, a mental resting place within the 4 ashramas in life. The day before the new moon, as in monthly Sivaratri, nivritti energy is strong, an excellent time for austerity and meditation. Six Shum words defined related to meditation-withdrawal: kashum, nikashum, shumnikashum, bishumnikashum, abibishumnikashum, haiiaiibishumnikashum. Drawing energy up in to the transcendental Source of energy. Imkaif: Absence of awareness aware of itself. Nonexperience.
