Attachment is the strongest block to realization.
It is not necessary to meet your guru on the physical plane. The guru is not external.
Everything is impermanent, except the love of God.
Love is the strongest medicine. It is more powerful than electricity.
The best service you can do is to keep your thoughts on God. Keep God in mind every minute.
Whatever may be guru - he may be a lunatic or a common person. Once you have accepted him, he is the lord of lords.
