What should be my regular spiritual practice?

There are so many ways to grow in Her Consciousness, including:
– taking the Mother’s Name as often as one can;
– offering one’s work in the beginning and again when it is over;
– concentrating upon Her image in the heart, meditating upon Sri Aurobindo and the Mother’s words;
– reading Savitri and Prayers and Meditations, reading the other books of Sri Aurobindo and the Mother;
– hearing about Them, keeping Their pictures and hearing Savitri music;
– taking up some work for Her in the spirit of service to Her, doing one hour work daily with no other purpose but the Mother’s service;
– making a visit to the Ashram;
– becoming conscious of our inner motives and rejecting all that stems from fear and desires;
– praying to Her in the morning after waking up and at night before sleeping;
– offering our thoughts and feelings and will and actions inwardly to the Mother
– practicing equanimity under changing conditions and situations;
– calling Peace until it is firmly established in us;
– learning to step back as a witness and act after reflection or a deeper inspiration;
– writing one’s inner and outer state to the Mother;
– aspiring within for opening to the Mother and consecration to Her;
– cultivating the right attitudes.

But most important is faith in Her Grace, sincerity in our thoughts, feelings and actions, and an increasing surrender to Her.
