Hari Om..to tell you honestly, I think sadhana is a 24x7(all day) thing and it can't be separated from normal living. It flows as an under current to all our transactions and thoughts, and it goes hand in hand with our day to day living. We play so many roles, mother, sister, friend, employee, householder, daughter etc etc. I think after adding one more role called seeker/devotee/disciple (whatever you might want to call it).. and identifying with it whole heartedly, all other roles suddenly become secondary to that and that gets called as sadhana. Birth is really 'identification', so in that sense, we are born again in the same life.
and this time with 'hope'..
