On Pranayama
Found these in my book 'Science of Pranayama' by Sri Swai Sivananda
Get up at 4 a.m. Meditate or do Japa for half an hour. Then do Asanas and Mudras. Take rest for 15 minutes. Then do Pranayama. Physical exercises can be conveniently combined with Asanas. If you have sufficient time at your disposal, you can have it after finishing all the Yogic exercises and meditation. Pranayama can also be performed as soon as you get up from bed just before Japa and meditation. It will make your body light and you will enjoy the meditation. You must have a routine according to your convenience and time.
The general order of doing Kriyas is: First do all Asanas, then Mudras, then Pranayama and then Dhyana. Since the early morning time is suitable for meditation, you can follow this order: Japa, Meditation, Asanas, Mudras and Pranayama. This is a better way. You can follow the order which is suitable to you. After doing Asanas, take rest for five minutes and then begin Pranayama.
Maximum benefit can be derived if Japa also is done during the practice of Asanas and Pranayama
It is always better to start Japa and meditation in the early morning at 4 a.m., as soon as you get up from bed. At this time the mind is quite calm and refreshed. You can have good concentration
First do Japa and meditation. Then you can take to Asana and Pranayama exercises. Then finish the course of practice by another short sitting in meditation.
If one controls the breath or Prana, the mind also is controlled. He who has controlled his mind has also controlled his breath. If one is suspended, the other is also suspended. If the mind and Prana are both controlled one gets liberation from the round of births and deaths and attains immortality. There is intimate connection between the mind, Prana and semen. If one controls the seminal energy, the mind and Prana are also controlled. He who has controlled his seminal energy has also controlled his Prana and mind
