Vijnana Bhairava Tantra
71: When great joy is obtained through any event such as meeting with relatives, one should meditate on that with one-pointedness, until the mind becomes absorbed and the bliss ever arises.
72: If one concentrates on eating and drinking and the happiness obtained by that joy of taste, from such contemplation of enjoyment arises the state of fullness, which then becomes supreme joy or bliss.
73: As a result of concentration on the pleasures of the senses, such as music or song, the yogi experience equal happiness or pleasure within. By being thus absorbed, the yogi ascends beyond the mind and becomes one with that supreme.
74: Wherever the mind of the individual finds satisfaction without agitation, let it be concentrated on that. In every such case the true nature of the highest bliss will manifest itself.
75: When sleep has not yet fully appeared or when one is about to fall asleep, and all the external objects have faded out of sight, then the state between sleep and waking is one on which one should concentrate. In that state the Supreme Goddess will reveal Herself.
