The strongest bondage for a Yogi is attachment, which makes one weak and ignorant. Maya or illusion is deeply rooted in attachment. When we are attached to or have desire for something, it becomes source of illusion for us. Those who are free from attachments and have directed their desires towards spiritual growth are free from the bondage of maya/illusion. The less attachment, the more inner strength.
Many people confuse attachment with love. But in attachment you become selfish, interested in your own pleasure, and you misuse love. You become possessive and try to gain the objects of your desires. Attachments creates bondage, while love bestows freedom. When yogis speak of non-attachment they are not teaching indifference, but are teaching how to genuinely and selflessly love others. Non-attachment properly understood, means love.
