According to Osho, non-attachment arises not by special effort for 'ordinary' people but by seeing that non-attachment is your very nature. Drop the search to acquire it; inquire how you drifted from it. Like water beyond hot and cold, awareness rests in the middle; when this is understood, attachment/renunciation fall away and your innate freedom flowers.
You don’t have to get non-attachment; it’s already you—just notice how you began clinging and relax back to your calm center.
