Eclecticism has no place in this path
"The seeker of the Absolute must have no object in life but the persistent pursuit of the Absolute, to which he bends all the power of his soul. To approach it in any other attitude, say with motives not strictly spiritual, or with a surfeited, insubordinate intellect, or to expect the Absolute to bend and yield its secrets in the first week or first month for one's own sake, for the sake of one's worldly achievements, illustrious ancestry or community, denotes a lack of the most elementary qualities that make one eligible for it. Eclecticism likewise has no place in this path: its application is poor, its understanding diffused, so are its spiritual yearnings.”
S. S. Cohen in “Advaitic Sadhana” p. 2 (1975)
