Selections from the "Tales of Prison Life" and "Uttarpara Speech" by Sri Aurobindo
The physical is not weak, it is inert, because inertia is its principle — it is meant to be an instrument.
The heart is part of the vital — it has to be controlled in the same way as the rest, by rejection of the wrong movements, by acceptance of the true psychic surrender which prevents all demand and clamour, by calling in the higher light and knowledge.
