Being present always keeps your soul in tune as you hit the high notes.

Spiritual life means that you live life in the realm of your soul and lead your life with love from that space.  You are empowered through a higher source that is revitalizing and uplifting.  You can feel such bliss that become peak experiences at times.  I remember sitting on a tram in San Francisco and reeling with love for each person who sat on the bus with me.  This is bliss and it lasts for periods of time.
Enlightened Masters experience this heightened realm all the time.  That is why it is uplifting to be in the presence of a Saint as they radiate this love from their core being.  They are bliss and love and don't contain it for their own benefit.  Actually the whole purpose of their life is to set others hearts alight with the flame of light and love.  This is how the world gets changed one by one.
What is important in the process of personal transformation is a total surrender and commitment to the process of purification.  My first teacher used to use the analogy of gold being made pure by the fire.  In the same way our hearts and minds are made pure by our practice of Meditation and the Grace of the Master.  Our relationship to a living Master can be described as a two winged bird.  One wing being our self effort and the other being the Master's Grace.  Purification is liberating as it literally lightens our load.  Have you ever felt the heaviness of a burden that is sometimes described as a saying "Carrying the burden of the world on your shoulders?"  You may feel a sense of doom in the pit of your stomach.  A state of being that we become accustomed.  It is not the real you.  You have to peel back the layers and become truly who you are.  It may mean letting go of anger and hurt.  The process is always guided and supported through Grace.  There is an inner longing to shake off all the conditioning that we have learned to identify with but is not our true self.
William Butler Yeates, "Vacillation."
My fiftieth year had come and gone.
I sat, a solitary man,
In a crowded London shop,
An open book and empty cup
On the marble table top.

While on the shop and street I gazed
My body for a moment blazed,
And twenty minutes, more or less,
It seemed so great my happiness,
That I was blessed, and could bless.
