Thank you for this advice:

"...it is impossible to truely understand the minfulness or vipassana meditation without practicing by yourself..."

Though I do practice observing my senses (cittas) as they arises, develop and fall away in sequences. I find recognition of each citta is much slower than its progression (a citta completes its life before I can properly know what it is).

I asked for more explanations so that 'we' can understand the Buddha Teaching better - not just reciting the words in Pali (or the translation).
