Hi Senin,
My name is Andrea, I am one of Gabrielle’s graduates from her teacher training.
With her permission I sometimes respond to forum posts, I hope that is ok with you too!
In answer to your question, there are many different ways to practice Pranayama.
Panayama means conscious breathing exercise that enables one to gather ‘prana’- life force – that can set one up for a strong and focused yoga class.
Its purpose remains unchanged wether you want to attach the word ‘life force’ to something spiritual or not.
Breathing is life after all!
It also helps to warm up the body internally.
Therefore I would say that there are many ways to practise it.
The purpose and the outcome define pranayama breathing exercise not the series of movement.
As to the discomfort, can you please tell which part of the exercise causes the pain in your neck?
Have a lovely day!
Namaste
=)
