If both ‘Shraddha’ and ‘Saburi’ are there, then there is definitely no problem in Sadhana. What happens often is that, when there is ‘Shraddha’, there is not enough ‘Saburi’ and, sometimes, ‘Saburi’ may be there, but no ‘Shraddha’. Both are necessary. Absolute, one-pointed total attention is required in our path, along with infinite patience.
