Maa, who was my Atma Yoga teacher, said this to me once, to realize God, 3 things are necessary.
She said –
Practice non stop your sadhana, it is like a spiritual breathing.
When you work , do your best and then surrender the result to the divine.
Serve all those who come to you.
And always ask for Grace. Ask for Grace to help you to surrender. Ask for Grace to help you to love more and to open your heart.
