This is a meditation based on the moment that The Báb declared His mission in Shiraz on May 22nd, 1844 as the Herald of "Him Whom God Shall Make Manifest".
This meditation is a guide through the physical experiences of Mullah Husayn soon after The Báb declared His mission. Excitement, awe, joy, wonderment are a few emotions that are encouraged to be felt in the physical body amongst others. This type of method and practice of meditation is considered quite advanced, and is encouraged to be practiced with caution.
If at any moment the emotions that are being asked to be experienced becomes too intense and burdensome on the body, immediately stop the meditation, or switch to another meditation, such as the Heart meditation which is a more gentle and mild meditation practice.
Everyone responds differently in each mediation, and some types of meditation work more for some than others, there is no good versus bad feelings, more so like on a scale of personal preferences and conduciveness to spiritual growth.
As this meditation is the hallmark of intensity of emotions experienced by the first recipient of a new Divine Revelation, it will inevitably be more intense in the emotions experienced and it's purpose is meant to be used for occasional inspiration, building of faith and encouragement, rather than a daily meditation practice.
Moderation is advised.
