Osho gives a personal meditation to a sannyasin in darshan.
Make it a point every night before you go to sleep to have a picture of me and to look into my eyes in the picture for two minutes. Just feel me so that I can continue working in your sleep. Then don’t do anything else, otherwise it will be a disturbance.
When you have done everything, the day is gone and you are ready to sleep, sit on the bed and look into the picture. Just feel my presence as if you are just sitting in front of me, and within three weeks you will be able to almost realise that I am there, surrounding you. Then go to sleep, so I will start working on you in your sleep and things will start happening.
Osho, Dance Your Way to God, Ch 5
