Orthodox hindu Vedas state:

As stated in the Taittiriya Upanisad (2.9): ". . . brahma puccham pratisöha . . ."

1] There is God’s energy known as anna-maya, dependence upon food for existence.
This is a materialistic realization of the Supreme.

2] Then, in prana-maya {after realizing the Supreme Absolute Truth in food, one can realize the Absolute Truth in the living symptoms or life forms.]

3] Then, there is jnana-maya [realization extended beyond the living symptoms to the point of thinking, feeling and willing]

4] Then there is vijnana-maya (Brahman realization) [in which the living entity’s mind and life symptoms are distinguished from the living entity himself.]

5] the next and supreme stage is ananda-maya [realization of the all-blissful nature]

Thus there are five stages of Brahman realization, which are called brahma puccham.

The first three—anna-maya, prana-maya and jnana-maya—involve the fields of activities of the living entities.

Transcendental to all these fields of activities is the Supreme Lord, who is called ananda-maya.

The Vedanta-sutra also describes the Supreme by saying, ananda-mayo ’bhyasat: the Supreme Personality of Godhead is by nature full of joy.

To enjoy His transcendental bliss, He expands into vijnana-maya, prana-maya, jnana-maya and anna-maya.

In the field of activities the living entity is considered to be the enjoyer, and different from him is the ananda-maya.

That means that if the living entity decides to enjoy in dovetailing himself with the ananda-maya, then he becomes perfect.

This is the real picture of the Supreme Lord as the supreme knower of the field, the living entity as the subordinate knower, and the nature of the field of activities.

One has to search for this truth in the Vedanta-sutra, or Brahma-sutra.

It is mentioned here that the codes of the Brahma-sutra are very nicely arranged according to cause and effect, ie:

A] na viyad ashruteh (2.3.2) — the field of activities,
B] natma shruteh (2.3.18) — the living entity, and
C] parat tu tac-chruteh (2.3.40) — the Supreme Lord, the summum bonum of all various entities.

When, by simply quite sitting mantra-meditation one stops paying attention to thoughts and thus withdraws the senses inward toward its center point of origin ---No further stimulai distracts the mind's attention ---that is when the meditator preceives bliss. This Bliss is there from the beginning ---yet the meditator is fully conditioned to be distracted by life's stimulai.

It would seem that intimate moments in bed are comprised with activities that ask the performers to focus there attention to only a single minded goal ---it is an Irony that of all daily activities are not appreciated with the same level of 'delighting in the mercy' of all the facilities because the senses are so dulled by material living.
