Sadhana is the backbone of spiritual realization. Grace is the cause for Spiritual realization. But the very cause for Grace is intention and the Sadhana that follows such intention. Only when Sadhana is committed, free of desire, in the direction of the Supreme, seeking His Grace, it can never be long-lasting and hence will be fruitless. Through Satsanga, one can increase and steepen one’s sadhana. Sadhana is indeed the single-most cause for any transformation of life, character and events.
