user11541: I am looking forward to develop 7 factors of enlightenment. The 7 factors of enlightenment are factors of mindfulness, investigation of principles, energy (viriya), rapture (piti), tranquility (passaddi), immersion (samadhi), and equanimity.
I have understood how to develop factors of mindfulness, investigation of principles and equanimity. 
However I am not sure how to develop the following:

Energy (viriya)  
Rapture (piti) 
Tranquility(passaddi) 
Immersion (samadhi)

(I guess Tranquility can be developed by becoming independent. If the answer to samadhi is to enter the first Jhana then my question will be how to enter it?)
So my question is: How to develop energy, rapture, tranquility and immersion? If you know answer to only one or few of the above factors then please post that as an answer. I will combine them. 

user12677: This is such a good question! 
Each of these steps includes a further development of 'clarity', hence the first two steps - of mindfulness and investigation - to get this going.  An inspiring source, for some people, is in the essays of Ajahn Jeff, of Wat Metta.  These can be found in accesstoinsight.org.  His approach is so practical and sensible.  
The sexual renunciation required for developing Steady Energy is just the gross aspect.  Steady Energy comes naturally out of constant practice when the mind becomes sufficiently calm.  Trying to develop this will only act against it.  This principle applies to all the remaining stages.
