Peter Heehs biography is, in my view, misleading and diabolic. I have already written much about it earlier. There are several beautiful biographies from which you can select.
Rishabh Chand: Sri Aurobindo, His Life Unique is best for the pre-Pondicherry period.
Satprem: Adventure of Consciousness is wonderful from the presentation of ideas.
AB Purani: Life of Sri Aurobindo is a standard biography, compact and comprehensive.
KR Srinivas Iyengar: Sri Aurobindo is quite good and exhaustive.
There are others but these four are factual and very good.
Affectionately,
