Samadhi is the result of many months of increasing and most loving Kriya Yoga

Years of practice - from novice to Samadhi - will lead to the point when you feel Kriya Pranayama is getting better and better each day. More love flows thru you, less sleep is needed and finally you feel that even many hours of Kriya Yoga each day are no longer work or duty but pure pleasure. You become hungry for more, feeling that God gets closer and closer to you.
Normal daily life, daily loving and caring work is best for all the years of preparation. The very same applies for the final weeks or even the final days before reaching Samadhi. You follow your daily routines, you do all your daily work, helping others, caring for others, loving others, taking care of your family ... one day during your advanced Kriya Yoga practice you will feel that you will be going beyond. Samadhi will happen to you as the result of all previous spiritual lessons properly done and all loving work accomplished in all the past many years. Samadhi will be a gentle transition from physical being to truly and purely spiritual being that becomes one with God - breathing stops smoothly while awareness increases and comfort or wellbeing increases manifold ... soon after breathless state the heart stops beating while at the same time you feel to fall in love - you feel to be flooded with love from God and to start your final journey home to God.
God is Love
You have learned by now to focus on important things in life and also have learned to drop all waste of time or waste of resources.
God has a firm place in your heart, in your life and in your home and work as well - hence you can rest assured that Samadhi will occur any time any place in your daily life-routine. In day time you work your full and normal work schedule - after that you do all your spiritual oriented duties in home and house ...
And each free minute or hour you spend doing your Kriya Yoga practiced as you feel necessary - just follow your inner guidance and you will know what and how to do all that leads to oneness with God.
These very weeks might be best to focus more than ever before on love and being loved, on enjoying love and fully absorbing love. Roses are excellent to prove that you have judged yourself lovable. Buy roses - for you - just for you and learn to enjoy their view, their fragrance and beauty. Absorb all love radiating from roses.
